The compact e-drive solution weighs under 4 lb and allows for seamless switching between e-assist and manual riding. The company claims it's the lightest and smallest bicycle e-drive (soon-to-be) available.
Cologne-based Velogical builds rim dynamos for powering bike lights, and at first glance, that's what the Velospeeder looks like. However, it's actually a sized-down e-drive that offers up to 600 watts of power and 29.5 lb.ft (40 Nm) of torque. At 3.5 lb (1.6 kg) for the entire package, it comes in much lighter than other e-drive kits. The current iteration uses a 92-Wh lithium-polymer battery that provides up to around 12.4 miles (20 km) of e-assist. Velogical says that the battery is light enough to carry a spare and easy to swap.
