Big Bang



Big Bang headlight



The Big Bang is now discontinued and we have no more left. However, we do have some spare parts in stock.

Wall plug adapter: $ 3.00 (Use this if you already have a voltage converter and only need to convert the plug)

Voltage Converter: $ 12.00 This converter takes the German plug of the Big Bang charger, and it plugs into a standard American/Canadian wall outlet. You don't need a plug converter with this voltage converter. It's all you need to charge the Big Bang.

Replacement Battery for Big Bang, Part # B&M497AT: $ 175.00

Replacement Charger for Big Bang, Part # B&M4477: $ 69.00

Replacement Offroad Fluter for Big Bang, Part # B&M497OFF: $ 10.50


The Big Bang's battery can be charged with a hub dynamo and the E-WERK. You must have a special cable to do this. Riding during the day, you can disconnect the Big Bang's headlight from its battery, and then charge the battery. Or, you can use the Big Bang to lengthen the run time of the Big Bang's battery while using the light.
