But the German-based Ruff Cycles may have wanted to pluck a motor out of its own backyard, opting for a German Bosch e-bike drive system.
The Ruff Cycles Biggie comes with two motor options: a Bosch Active Line or Bosch Performance CX Line motor.
Both are listed at 250W, which keeps them legal in the EU. Both also definitely put out more than 250W of power.
Because European motor manufacturers are hamstrung by low-power e-bike regulations limiting them to 250W, they all claim a nominal 250W rating while publishing actual torque ratings. The torque ratings are not regulated, and thus allow manufacturers to more accurately convey the true “oomph” of their motors. For example, the smaller Bosch Active Line motor puts out a decent 40 Nm of torque, while the powerhouse Bosch Performance CX Line motor more than doubles that torque at 85 Nm.
Both are limited to a somewhat disappointing 25 km/h (15.5 mph) top speed – again due to EU electric bike regulations.
Customers can choose between two Bosch battery packs, a 300Wh or 500Wh pack. Both are rather small for a bike of this style, but the low top speed and lack of a hand throttle make the packs more or less sufficient since the motors can’t draw as much power as American electric mini-bikes like those made by Super73, Juiced Bikes, Ariel Rider, and others known for high-power electric bikes.
The powder-coated steel frame on the Ruff Cycles Biggie won’t do the bike’s weight any favors, and in fact the company has refrained from publishing the weight of the bike. So far it is listed as “TBA.”
But don’t expect this e-bike to be a lightweight. Moped and mini-bike electric bicycles are notoriously heavy, with their weight normally offset by the inclusion of a throttle. Without a throttle on the Ruff Cycles Biggie, riders will be relying on that Bosch mid-drive motor fully for pedal assist to get rolling.
The Biggie won’t be available until next year, when it will come with an expected price of €3,399 (approximately US $3,990). That’s a pretty penny, but the bike also sports a number of high-end parts to attempt to justify that high-end price.
Riders get an Enviolo continuously variable transmission paired with that Bosch mid-driver motor, Magura hydraulic disc brakes, high-end Tyron tires, and European manufacturing. The company doesn’t just assemble e-bikes locally on Chinese frames; they actually build the bikes from the ground up starting from the bare frame tubes. So despite the high price, there’s some real value here.
