Additionally, because the capacitor stores a limited amount of power, those devices are able to keep running when the bike is stopped for short periods. That hub in turn regulates the current, feeding it out stably and consistently (again via wires) regardless of cycling speed.ĭelivering a maximum of 20 watts, CadenceX isn't intended to power electric bikes' motors, but it could reportedly power just about any other bicycle-mounted electronic device – these could include lights, electronic shifting systems, phone chargers, cycling computers or actioncams. That spinning motion generates electricity, which is sent via wiring to a capacitor-equipped handlebar-mounted Smart Power Hub. Remember those "bottle"-type dynamos that rubbed against the side of your bike tire in order to power the lights? Well, they've gotten a high-tech makeover, in the form of the fork-mounted CadenceX generator – its creators say that it can replace the batteries currently needed for all bicycle electronics.Ĭreated by Chicago-based startup PedalCell, the device features a rubber-edged wheel that spins as it presses lightly against the bike's front wheel rim.
