This guy electrified his vintage Honda CB100
Adam Waldron is a British designer based in London, and according to his site, he also “designs and manufactures products with an emphasis on sustainability and reuse”. One of his projects addressed “sustainability and reuse” with a motorcycle.
For sustainability, he wanted an electric motorcycle, to reuse it, he had a “failed” cafe racer project. The base bike Waldron used was a 1980s Honda CB100. The sale included a load of spare parts and a gas engine that Waldron went to work removing from the frame.
The next phase of the project was to procure an electric motor and battery from a specialist in China. Waldron’s creation uses a hub motor that gets its power from a main battery located where the 100cc motor sat. Waldron has designed and manufactured its own bike-friendly battery box. According to him, the bike can travel up to 55 miles on a full battery.
Besides the obvious motor swap, Waldron also mentioned that the bike’s rear brake was changed from a cable-actuated unit to a hydraulic unit, which makes sense considering the hub would likely have required the rear drums to be replaced. . The rear brake accompanies the front brake, which retains its solid disc, and the throttle which is always in the same position as a standard motorcycle.
Anything original Waldron could keep, he did. Aside from the engine, rear brake and hub assembly being shaken out, most of the bike remains the same. The seat, reservoir, front hub and fork, all lights and frame remain largely the same.
Due to the simplicity of the bike, reliability should be good, but usability might be a bit questionable on the highway since Waldron mentions that the “CB100-E” top speed is pegged at 35 miles per hour. What’s most impressive is that the full price of the bike was under £2,000, or around US$2,400. Performance is similar to e-bikes with around 50cc of power, but it features an aesthetic that many custom enthusiasts can follow.
