Back to the bike. I’ve gotta be honest, it doesn’t look half bad. The battery fits into the downtube, which is way better than those crazy brackets you see on cheap ebikes. The welds are also smoothed over, like an old Aluminum Cannondale. The drivetrain is a mix of parts, with Shimano Altus in the rear. Altus is a mountain bike groupset, but on the very low end.
The Dew-E packs functionality and fun into a rather traditional and conservative package. Front and rear fenders, integrated Busch & Müller front and rear lights, and a built-in Abus wheel lock make this a very practical commuter bike. An 11-34t 9-speed cassette and 1.75-inch tires provide versatility: You’ll stay smooth over rough city streets and zip down gravel bike paths with confidence. Front and rear rack mounts also give you the chance to outfit this bike for carrying more cargo or supplies for a longer day on the bike. Whichever way you think you’ll be riding an e-bike, this bike deserves a second look.
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.
