Riding position: You also may wish to check out an e-bike’s riding position before investing in it. For short trips, the riding position might not make much difference, but for long journeys, the upright "Dutch" style with pulled-back handlebars is very comfortable – particularly for tall riders. The same goes for mountain bike styles, though these bikes are not often designed to actually go off-road.
The wiring could be better, but I think I’m going to make some adjustments to that myself. It’s also worth noting that the motor is in the rear hub just like a basic commuter ebike. This will affect the way it feels, as bottom bracket motors give a more seamless “pedal assist” experience. Of course, this bike seems like it’s made as practical transportation. To me, anything that gets cars off the road is a good thing so lets take it for a ride.

The F1-trained engineers at William Advanced Engineering assisted with the electrical parts and the result is a 250W motor that provides pedal assistance via the front hub – which is a highly unusual approach –  drawing power from a 300Wh battery pack that sits in a bag and goes on the front where the Brompton luggage rack would normally sit. You can also opt for a larger bag that holds both the battery and your spare suit or laptop or whatever. 

Thank you Clean Republic for coming to my rescue when I had a battery issue last year. Under Warranty at 11.5 months, they without hesitation sent me an entire new $355 Battery pack when mine began to fail. I've gotten so much life, miles, and usage out of my Hill Topper from this first one and am about to replace the batteries again from so much more love on them. Seems the hub motor is going to last forever and that's what counts! Thanks guys! :)


“The new tariffs that have hit our industry (and so many others) will be difficult to navigate. Not because they will hurt our business but because they hurt the American consumer. If the US were more manufacturing friendly I think most bike companies would be happy to manufacture here. However it is very expensive to manufacture in the US and overseas manufacturing is the only real way to offer the American consumer potentially life changing products.”

E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque and others are quieter. But generally all four make good options. Look for motor output (in watts) which will give you an idea of total power. But watt hours (Wh) is perhaps a better figure to use—it takes into account battery output and life to give a truer reflection of power.
