Intro to Ebikes

Electric bikes are a new and promising alternative form of urban transportation. They provide all the advantages of a regular bicycle: fun exercise, free parking, zero emissions, and freedom from gridlock, while eliminating one of the bicycle's more serious drawbacks, lack of power. Imagine pedalling up a hill as comfortably as riding down, that's what the e-bike experience is all about. In most situations in the city, riding an electric bike will be faster and cheaper than either car or public transit...

Ebike Troubleshooting

One of the things about meshing complex electrical and mechanical systems together is that occasionally things can go wrong! We've seen more than our fair share of ebike issues come and go over the years - from shot ball bearings, seized freewheels and stripped threads to defective hall sensors, blown mosfets and connector issues. We've learnt a lot along the way and continue to use this experience to help create more efficient and more reliable electric bikes...

Ebike Wheel Building Tips

There are many good print and online references for lacing bicycle wheels. Many will defer to Sheldon Brown, Brandt's Bicycle Wheel Book, and others. However, a lot of the points and details with a conventional bicycle hubs don't necessarily apply to hub motors with their much larger flange diameter.

Hub Motor Info

Slick and discreet, the hub motor is steadily emerging as the standard drive method for not just ebikes, but scooters, solar cars, and many other light electric vehicles. With a hub motor conversion, there is no need for external mounting brackets and drive chains to support a motor and transmission. Instead all of this is contained inside the wheel which mounts on your bike like any other wheel. There are two basic categories of hub motors: direct drive and geared...

Battery Info

The battery pack is one of the defining aspects of any PEV project; by and large it determines the weight, range, and cost of the vehicle. For these reasons a solid understanding of the various battery types is more than a little useful...
