On the Subject of Cargo

June 18, 2015 11:18:22 AM PDT

Well, the informal Cargo Bike Championships were a real blast, with last minute entries bringing in a total to 37 participants. The event spirit wonderfully captured on video by Iaco Rocher here:

We wanted to publicly congratulate the two winners of prizes sponsored by Grin. Philip Marciniak got a V3 Cycle Analyst and LED light kit for the best custom built ebike for his scratch build longjohn style bike used for his appliance repair business.

And Fabrizio Cross got a $200 gift certificate for setting the electric speed record for the fastest lap on full scratch-built semi recumbent bike, with room for both children on the back. This is one of those builds that blurs the lines a bit between ebikes and higher powered 2-wheelers, but the wide scooter wheels and full suspension do wonders to smooth travel on the bumpy roads of his hometown on Hornby Island.

Also a shout out to Stuart and the Lecicle, who showed up with the best family bike designed by kids that we’ve ever seen!

Yuba Cycle Stokers

After a very successful pilot run, we’ve now done a full production and release of the Cycle Stoker kit for Yuba Mundo cargo bikes. Thanks to all those who’ve participated to resolve any kinks as we expanded this kit to the popular Yuba platform. We’ve updated the Cycle Stoker info page has recently to include a lot more details about this mid-drive option to answer questions for anyone else who is considering it

For those still awaiting a Cycle Stoker kit for Big Dummy cargo bikes, that will be next inline on this project.

Bike To Work, Bike for Errands, Bike to BBQ!

May 28, 2015 12:50:39 PM PDT

This has been an awesome time for alternative transportation in Vancouver. Not only did we learn that non-car trips (biking, walking, transit) outnumbered private vehicle trips for the first time ever; cycling use in the city jumped another 20% last year, the hopelessly archaic Business Improvement Association has finally acknowledged that bike lanes are good for business, and the weather and turn-out for Bike to Work Week has been amazing.  We’d love to know exactly how much of a role electric assist is playing in that, but it’s no doubt a very large factor for some. 


Cargo Race TrackLet’s not forget to celebrate all this at the wrap-up BBQ on Friday at Creekside Park besides Science World. The full details of the Cargo Bike Championship have been posted to the participants. It includes a race where you pick up more cargo on each lap and a host of prize categories, and should be good fun with nearly two dozen cargo bikes of all types in the mix.

 

For the categories of “Best Custom Built Cargo Bike”, and “Fastest Time with Electric Assist” we’ll be awarding winners with their choice of:

  • A) A Cycle Satiator universal battery charger.
  • B) A Cycle Analyst and front/rear ebike lighting system
  • C) A $300 Grin Credit towards the purchase of an eZee conversion kit, or
  • D) A $200 gift certificate for anything at Grin

For all the other categories we’ll be giving away gourmet popsicles from our friend Johnny, who’s been making and selling unbelievably tasty cold treats from his mobile trike:

Because of this event, we will be closing our shop early on Friday at 4pm so that all our staff can participate. To our local customers and friends, we hope to see you there too!

New CA2 Firmware to Test

May 13, 2015 3:14:46 PM PDT

The classic V2 Cycle Analyst series hasn’t seen a firmware update in several years, and it’s time we fix that.  For anyone with a V2.3 Cycle Analyst, we’ve now got two more firmware options that you might like, both featuring the battery state-of-charge (SOC) icon previously only available with the V3 devices.

CA Marine Firmware Splash ScreenThe first is a special Marine Firmware that we developed for a Dutch dealer. This trimmed down code is ideal for anyone using the V2 CA as a power monitoring device in applications where there is no need for speed and distance tracking, just watts, amp-hours, volts etc.  The Auxiliary Potentiometer Input has been re-purposed as a temperature input for thermal monitoring if desired too.

 
Marine Firmware, Main Screen Main Screen with Temperature Percent Recharge Screen
 Main Screen showing Amp Hours and Battery SOC Icon  Amp-hours toggles to temperature readout if enabled  Display of recharge percentage and recharging Ah



CA V2.4 Splash Screen

The second firmware update is a general purpose V2.4 release for vehicle usage. To a first order, this is very much like the V2.3 CA code with the addition of a battery icon, but there are many changes in the back-end and setup menus too which should be appreciated, including better rejection of spurious speed readings if the spoke magnet and pickup sensor become misaligned.

 

CA V2.4 Features

You can update any of the V2.3 Cycle Analyst devices (But not V2.25 and earlier) using the same software tool and programming cable as a V3 CA, as explained here. This update will reset your total life cycle statistics, so before reflashing be sure to write down your total Amp-hours, Distance, Battery Cycles, and other custom settings so that you can re-enter those values later.

So if you have an inkling to try out the latest, please load the code above and send us your feedback.

Get your Cargo Rolling - May 29th

May 8, 2015 11:23:39 PM PDT

There are few things we love more than riding around Vancouver hauling stuff on electric cargo bikes; turning heads and getting high fives and thumbs up while shuttling goods back to our shop at Grin. So we were smitten to see that Vancouver will be hosting it’s first every Cargo Bike Championship on May 29th, right at the end of Bike to Work Week, courtesy of Modacity and HUB. Read about it right here.

What’s a Cargo Bike Championship exactly? We don’t really know, but we figure it’s going to involve some kind of informal cargo hauling contest, some kind of vehicle rally, some kind of judging, and of course prizes! On that front we’re going to be sponsoring some very big awards, like Satiators and Lumenators and perhaps even a full conversion kit. We’ll update on the details as they materialize.

In the meantime though, if you ride a cargo bike of any kind here in Vancouver, whether for transporting kids or your full suite of work tools, then come help us to showcase this other side of utility cycling. Modacity is looking for participants to register their bikes by May 18th, so get your details in and lets make this a great little rally. It's timed to coincide with the wrap-up BBQ at creekside park from 4-7pm, where there will be tons of cyclists gathered and free foodstuff too.

More Goods on Amazon

May 2, 2015 6:56:31 PM PDT

Purchase a Satiator via Amazon.com

Last year around this time we got our Torque Arms listed and stocked at Amazon for faster and cheaper shipping to US customers. Well we can now add to the mix the Grin Lumenators Lights, USB Power Adapter, and Cycle Satiator Charger too. So if you're after just one of these items and are in the United States, then you should find Amazon can deliver it to you quicker than we can here in Canada.

Vancouver EV Expo, Friday Apr 24th 5:30-9:30pm

April 20, 2015 3:39:28 AM PDT

In our first community event of 2015, we’ll be participating in the BC Sustainable Energy Association’s (BCSEA) electric vehicle faire, taking place this Friday evening at Science World from 5:30-9:30pm.   This is being promoted as an opportunity to learn about EV’s, meet local EV businesses, and test ride any number of electric vehicles. Additional information is here:

BCSEA Page: http://www.bcsea.org/bcsea-vancouvers-electric-vehicle-fair-2015
Facebook: https://www.facebook.com/BCSEAVancouver

So come on out, it’s not free but it should be worth it. We’ll be there to balance out the heavy presence of commercial electric cars with a full suite of electric cargo bikes, trikes, folders, and longboards, all available to test riding.  

And if you do have a nice homemade electric bike or other PEV that you’d like to show off, it’s not too late to sign up as an exhibitor. Please either contact us or BCSEA directly to be a part. You can help bring awareness to the massive impact that ebikes can have as a viable transportation option.  After all, you don’t need 4 wheels, a roof, a trunk, and 2000lb of steel and batteries to get around town and have fun doing so.

Conversion Kits Better Explained

April 15, 2015 12:52:09 AM PDT

We’ve recently changed how ebike conversion kits are presented on our website in a way that hopefully makes it easier to find the best option for your bike. At the center of this is a new conversion kit summary page that highlights the key features of every Grin kit and the applications and bicycle types where they shine.

Our mission is always to create conversion kits that use universal standards and interchangeable components, and address interesting niche applications that aren’t well serviced by other “one size fits all” systems.

Bromptons Included

April 15, 2015 12:51:38 AM PDT

On the new kit front, you’ll now see two dedicated Brompton specific packages based around the Crystalyte NSM and SAW20 hub motors. We’ve customized the cable lengths and controller / Cycle Analyst mounting brackets to fit neatly on these unusual bike frames, had the motor axles machined with a 8mm axle flats and a 75mm length to be a drop in fit with the Brompton forks, and even made custom 8mm mini torque arms too. No fork spreading or dropout filing required, these kits are ready for primetime, and feature the same upgrade options of PAS and Torque sensing pedalec control as our other systems.

Brompton Kit

Have a look at the Brompton Kit info page where we’ve explained the options and compiled a detailed installation guide with plenty of photographs and pointers on how to put things together right. This is our first time preparing a kit install guide in many years, and we’d welcome any feedback as this will become a template for other conversion kit installation pages soon to come.

Unlaced Front and Rear eZee HubsWe’ve got a nice update for those like doing things a little bit custom. The high performance V2 eZee hub motors have only traditionally been available as part of a complete built up wheel, laced with a rim, tire and tube, which added a lot of wasted expense for those wanting a different diameter or rim type.  Well we had a recent shipment arrive of pure unlaced eZee motors both front and rear, permitting eZee motor systems in a custom wheel build.

Included in these unlaced motors is a new fast 350 rpm winding, which will help 16” and 20” wheels get up to a decent road speed without the need for a high voltage battery. They’re a bit quicker than the normal 300 rpm motors that are in the 20” eZee kits, and have been added to our simulator page too.    

Custom Builds

Custom Laced Hub MotorTo facilitate the purchase of custom built wheels, we’ve also created a new part on our store site that lets you select any available hub, spokes, and rim option from a dropdown menu. That enables you to specify the best hand-laced motor wheel for your project rather than relying on stock kits.

 

A Suitable Fat Rim

DHL65 Fat RimOne of the rim options you’ll see listed is a 65mm wide Weinmann rim for fat tire bikes. With the recent updates to our spoke calculator it’s much easier to figure out the optimum lacing and dishing strategy for a fat tire build and these particular rims have a close enough left and right hole offset that they can work well with most motors.  

If you are doing a custom fatbike conversion, the best approach is to select a rear hub motor and use this on the front fork of your bike for a front wheel drive. Most fat bike forks have a 135mm dropout width, the same as a standard rear mountain bike hub.

Spoke Calculator Phase 2 Enhancements

March 7, 2015 9:45:19 PM PST

Well who would have guessed that the improved spoke calculator we put online last summer has been used to make over 75,000 spoke length calculations! We imagine only a small fraction of those turned into laced up hub motors, but it feels good to see our tools get put to such good use.

Spoke Calculations Performed to Date
We've now wrapped up the the second phase of this project to include a dimensionally correct cutaway edge view of the laced motor so that you can see the effects of dishing, spoke hole offsets, and even of lacing the spokes with the spoke elbows inside or outside of the motor flange. We're trying to turn this into the ultimate wheel lacing resource for ebike enthusiasts and welcome any additional feedback. Have a look and play around!

Ebike Spoke Calculator with Side and Edge View Drawings

Under the calculator results are full descriptions and explanations for the various fields, and we've updated all the hub motors in our database to include the offset from the flanges to the axle center for dishing considerations.

One of the key issues we wanted to illustrate was the importance of having the spoke elbows on either the inside or outside of the hub flange in different scenarios. This can be a significant consideration when lacing hub motors which often have spoke flanges spaced much closer together than a normal bike hub. We also wanted to make it easier to let people do hub lacing into Fat Bike rims which tend to have large offsets between the left and right holes, and included a simple "swap spokes" button to gain better triangulation.

Satiator Charge Simulator

February 11, 2015 2:03:23 AM PST

Hey guys and gals, check it out:

Satiator Charge Simulator Example Graph

We've completed what is surely the first online lithium battery charging simulator, with accurate renditions of the constant power, constant current, and constant voltage charge regimes. With this tool, not only can you see just how long it will take to charge a given battery type using the Cycle Satiator, you can also figure out the exact voltage profile for partial charge levels, and then download the resulting profiles right to your Satiator Charger.

We're hoping that this takes some of the mystery out of designing custom charge profiles for your battery and encourages you to produce partial charge routines to enhance your pack's longevity. With good management you can often make your expensive lithium battery pack give 2-3 times as many discharge cycles as it would with the stock generic chargers, and have the satiator handily pay for itself just on reduced battery replacement costs alone.

Smooth Controllers, Stoked Yubas, Happy Holidays

December 19, 2014 2:06:45 AM PST

Hey you'd think with the launch of the Satiator we'd take a little break and relax for the holidays, but not at all.

Field Oriented BAC500+ Controllers

Many of our custom EV projects over the past few years have made use of an advanced Field Oriented Motor Controller from ASI (Accelerated Systems Inc.) of Toronto, rather than the more generic imported Infineon devices. We've talked about these before, and have now made a small pilot batch generally available to the enterprising public.

Some Evolution of the BAC500+ Field Oriented Controller Enclosure

Made almost 100% in Canada, this BAC500+ controller in a hardcoat anodized CNC'd enclosure can measurably increase your motor efficiency and torque output at low speeds, run sensorless with even the highest RPM motors, use field weakening to increase the top-end speed, and remove the motor buzz from even noisiest of hubs.

For more information, have a look the descriptions and test results in the ES forum thread. We are down to single digit quantities remaining for those who who are tech savvy and want to taste the future of ebike control.

Cycle Stoking a Yuba

On another front, we renamed the Right Side Drive Stokemonkey to the Cycle Stoker several months back, and are now pilot testing a new model custom fit for the Yuba Mundo cargo bikes. Mid-drives like the Bafang BBS02 have made the rounds lately but this stands apart:

Cycle Stoker Prototype on a Yuba Mundo

  • Patterson 2-speed crankset, gives the equivalent of a 62T chainring for unprecedented high speed gear ratios even at a comfortable pedal cadence
  • Provides true Proportional Torque Assistance with all the custom settings of a V3 Cycle Analyst to dial in the desired performance
  • Uses of standard bicycle chain and bicycle components for the entire drive transmission, no special proprietary gears in the mix. 
 

If you have a Yuba Mundo bike and like being an early product tester to help work through any early release kinks, then please be in touch as we should have a half dozen kits ready by early January.

Grin Staff wishing you a Merry Christmas, (you won't find us in matching uniform like this too often.)

Finally, we at team Grin want to wish you all a Merry Christmas. We'll generally stay open with reduced staffing during the holiday but should still keep up on all the online orders. And in case you didn't see it, the -20% Satiator Promo for loyal customers will continue until the end of the December if you want to treat yourself to a little gift.

Blazing Speeds but Lost Emails

December 4, 2014 1:23:51 PM PST

We apologize that our webpage was down for maintenance much of yesterday. We were upgrading servers in order to make our site faster and better at handling high traffic. Now that the migration is finished you'll notice quite a dramatic improvement in the page load times when your browse our website.  

Unfortunately there was a time window yesterday evening and night when emails to any ebikes.ca address could have bounced. So if you sent us an message and don't receive the usual timely reply, there is a chance we did not receive it and you might want to forward the email along again.  Otherwise we hope you all enjoy the much snappier ebikes.ca !

Satiator Launch

December 1, 2014 3:42:21 PM PST

This is a proud moment for all of us at Grin. After three years of development and 6 months of beta field testing we’re now launching the Cycle Satiator in full capacity. For anyone who’s been fed up with the overall shoddiness of battery chargers available for electric bikes, this should get you salivating.

Please click the link above for more information, and also check out the endless-sphere discussion thread for the most immediate updates on firmware and software enhancements and our development vision.

Toast from the Satiator Engineering Team (Dan, Michael, Justin, Rob, Robbie, Dallas, +Shivan [not shown])

We managed to bring the Satiator into production without any kickstarter campaign or venture financing. Instead, this whole project was made possible by all the loyal customers and enthusiasts who caught the ebike bug and have been patronizing our shop over the years. Your business and your encouraging feedback has kept us motivated to keep developing new ebike technology, and well that's what we've been doing.

Time to Pay You Back

As a thank you, we’re giving a 20% ($60) discount on the Satiator from now until Boxing Day to anyone who has purchased either 2 or more Cycle Analyst devices from us, or has spent over $2000 in other parts from our shop. If you fit in this camp and like what you see, then simply email us with your order history and make sure you have an account setup on our current website, and we will hook you up.  Your faith in our business always has been and will be much appreciated.

We all but gave up on Nine Continent hub motors in recent times for a lot of reasons (inadequate disc clearance, poor paint job, inconsistent wheel lacing, improper connector crimping etc.). But things change, and we were truly blown away when we got samples of their latest 2014 model of rear motor this summer. It was one of several motors we’ve been evaluating that finally uses splined cassette freehubs rather than screw-on freewheels for the rear cog set.

9C Cassette Motor Features

  • Shimano Compatible Cassette Freehub
  • 30mm Wide Stator Core (vs 27mm in older model)
  • 20mm Clearance for Disk Calipers
  • Side Axle Wire Exit
  • 10K Thermistor for Temperature Sensing
  • Paired spoke holes
  • Diecast aluminum stator core
  • Future tech styling

 

We’ve now got a large supply of these available in a very fast (3004), fast (3006), and medium speed (3007) winding, both as bare motors or in a complete kit form.

 

The performances are fully modeled on the motor simulator (as NineCont 300X), on our spoke calculator, and we’ve produced a mechanical diagram of all the key dimensions from our 3D CAD model. That should be sufficient data to have you sold!

Bare Hubs for Sale Complete Conversion Kits

We also made the decision to stock them all unlaced, given you the option of low cost international shipping, or having a quality hand-built wheel custom laced into the rim of your choice with butted Sapim spokes. As part of this process, we’ve increased the range and type of rims we carry, adding a new PR17 series in 20”, 24”, 26”, and 700c. All these goods are in stock and ready to ship for your winter build projects.

Grin Dealer Locator Tab

There’s a new tab on our website that makes it easier to find our Grin distributed products from a local supplier.  Click on the “Dealers” button above to see our list of businesses around the world who have been great partners in getting electric bike gear into your hands.

Dealer Locator Filtering

We’ve tried to make it easy to filter by general product categories and geographic region so you can see if there is a business in your area that carries the parts you are after. If so, buying local can save on shipping, provide nearby service and support, and connect you to your local ebike community. So have a look today and see if there are dealers in your neighborhood to connect with.

These business partners all play crucial roles in the growth and development of the electric bicycle movement, and we’d like to publicly thank them for the many years of sticking together through good times and bad. It’s been a ride and collectively dealers now account for over 60% of our supplied goods.

Crystalyte Updates Aplenty

October 12, 2014 4:08:00 PM PDT

Last month we received what was one of our largest sea shipments of Crystalyte motors to date, large because there were so many new motor models and enhancements to get us excited. Here is the short summary:

Crown motors with Normal Spoke Flange

Previously, the large Crown motors had a pseudo straight-pull spoke design which meant custom wheel builds or even run of the mill spoke replacement was a great inconvenience. Well no more, they’ve now been retooled with a regular flange taking standard spokes, giving freedom to custom lace at will.

Crown motor spokes, straight pull versus regular

Narrower Crown motors

As well, we’ve received a narrower version of the Crown motor with a 30mm wide stator, which allows it to fit in a 135mm bike dropout with a 7-8 speed freewheel (Normal Crown motors are really for 1 or 3 speed freewheels). Although that also means less power and torque than the 40mm Crown hubs, it makes for a much more rideable bike conversion.

Comparison of the 30 and 40mm Crown Hubs

NSM and narrow SAW motors for folding bikes

We’re also introducing two new motor series designed for the special requirements of folding bikes with 75mm fork dropouts and small diameter wheels.  The Crystalyte NSM motor is the smallest direct drive hub we have seen, and is ideal for Brompton and Tikit conversions with 200-300 watt assist levels. The 20mm SAW motor is larger in diameter for better torque, power, and efficiency, at the expense of a bit more weight. Both come with 75mm axles that are machined with 8mm axle flats for a drop-in fit on Brompton forks.  

Crystalyte SAW20 and NSM Motors

The SAW motor we also have stocked in a larger 20” wheel suitable for the range of Dahon folders. We will be building more dedicated kit packages around these smaller wheels for easy installation with Brompton, Bike Friday Tikit, and Dahon bikes, but for now have the motors themselves available for those doing a DIY build.

Folded Electric Brompton with NSM Motor Folded Electric Tikit with NSM Motor

Unlaced with Options

Finally we’ve increased the availability of motors stocked unlaced, including front and rear H series motors and the Crown hubs as well. This simplifies those doing custom wheel builds for fat tire bikes or rim matching, and reduces shipping cost significantly for overseas orders.  

For all of these new hubs, we’ve created full 3-D CAD models and also characterized their performance behavior and put them on the motor simulator page accordingly.

Battery Bags

RB3 Battery BagWe’ve also got a good stock of the Crystalyte rear trunk bag as a battery enclosure option for the Naked Allcell battery packs. This as a built-in wiring harness with an on/off switch, so that you don’t need to rely on unplugging and plugging connectors, and has sufficient ground and side padding to keep the heat-shrunk packs protected.

Return to Vancouver and Thanks to our Global Friends

September 22, 2014 1:54:01 AM PDT

At the start of August, Justin and Anne-Sophie packed up a pair of electric Brompton bikes, some competition unicycles, and a small stash of clothes for what was nearly a 7 week world tour. This included joining the 17th international unicycle convention in Montreal, touring through France, Germany, and Switzerland to meet many of our European dealers face to face, attending the Eurobike show in Friedrichshaven, the Interbike show in Vegas, and finally spending a good week in the UK with some of our English comrades in crime.

So we’d like to publicly thank all those who made this such a great adventure. From Martin and Bobby for taming the beast at Unicon, to Philippe, Jean-Pascal, Andreas, Florian, and Reinhard for the accommodation through Europe. To Guillaume, Jules, and Tristan for such good company at Eurobike, and Stefan + the Radkutsche crew for the t-shirts and making our day. Miles you were a kind host with mind-blowing knowledge, and Steve it’s great to meet early pioneers. And finally to Ron, Tora, Paul, Ching, Wake, and everyone else at Interbike. We’ll hopefully see you next year.

ISIS Torque Sensing Bottom Bracket

July 27, 2014 3:02:45 AM PDT

A number of people with modern bikes have been hesitant to add a torque sensing bottom bracket to their ebikes because it meant changing over their cranksets to a square taper model as well.

Torque Sensing BB with ISIS Spindle

Well, at least there is one choice for a splined interface. The company NCTE has produced a torque sensor that has the same electrical specifications as the THUN devices, but which uses an ISIS spindle. We've got a 128mm spindle length model in stock for those with ISIS cranks keen to try it out.
