SunUp Eco Bicycle Spoke Dynamo

The SunUp Eco Spoke dynamo is an alternative to generator-based lighting systems. Unlike a hub dynamo, it can be installed on most standard adult-sized bicycles without the complication of changing or rebuilding the front wheel. According to SunUp, the Eco spoke dynamo is the most efficient bicycle generator on the market.

The SunUp Eco spoke dynamo has an efficiency of 84% meaning that it requires less than 4 watts of kinetic energy to generate 3 watts of power for your lights. SunUp recommends this spoke dynamo for use only with LED bicycle lamps, not traditional incandescent lamps, which are compatible but will produce adequate light only at higher speeds.

SunUp Eco Spoke is a three phase dynamo
Unlike standard hub dynamos, which are one phase, the SunUp Eco Spoke is a three phase dynamo. The advantages of three phase spoke dynamos are more efficiency, the production of more stable electricity (LEDs will not flicker at low speeds), and it produces direct current (DC) as opposed to alternating current (AC).

SunUp Eco also offers a Powerbank that can harness unused power from their spoke dynamo when the lights are not on, to charge a 2000 mAh lithium ion cell that can supply power to USB standard electronic devices.
