The BCB Take
The Ultra Bee C isn't chasing headline power. At 12.5 kW and just 84.8 kg, it's all about keeping things light, nimble and controllable when the trail gets messy. With 239 mm of suspension travel, 318 mm of ground clearance and 19-inch wheels, the hardware backs that up.
The clever stuff is in the details. Three levels of SRTC traction control, four riding modes and reverse give you plenty of control over how the bike behaves. It's not the most powerful electric off-roader out there, but at less than 85 kg, it might be one of the most fun to throw around.
Ride safe, folks.
