Bosch, the most prevalent purveyor of motors for the electrified contingent, reigned supreme as mid-drives dominated the scene; similar versions of their motor were promulgated by Brose, Yamaha, TransX and Shimano, all promising that their system was superior. One of the more interesting mid-drives was a coaxial motor produced by eProdigy, available on a variety of their bikes. Many manufacturers distinguished their e-bikes from the others with options for very large capacity or piggy-back batteries promising ranges which were unavailable previously.
My anticipation of this event has been building to a crescendo since the announcement of an electric mountain bike race at the venue. This is the icing on a cake that overflows with new e-products and the opportunity to learn more about the rapidly evolving technology.
There are many different types of bikes on the market, this makes it difficult sometimes to work out if one of our electric bike kits will be a good fit or not. We hope that this will help you with the major points to look out for, making it an easy choice.
We have designed our kits to fit as broad a range of bikes as possible, and by checking a couple of measurements, you can be positive of a good fit.
First, the axle slot width. These are standard with the majority of bikes coming with a 10mm width. This is where the motor axle will fit in; if your bike measures up at approximately 10mm then you are ok for this measurement.
Next is the dropout width.
This requirement will differ based on whether you opt for a front or rear motor. First the front motor. The width of the dropout should be approximately 100mm, if it is out by +/- 5mm that is ok.
For a rear motor, you will need 135mm width between dropouts, +/- 5mm.
I’ve wanted an electric car for many years now, at least as many as I’ve wanted an electric bike. But the cost seemed prohibitive, even more so than an e-bike. I’d considered the options and decided that I’d have to wait.
