About the Motor, Controller and Batteries!

250 Watts to 800 Watts variable power

Power is supplied by the modular LiGo battery packs from Grin Technology. A modular battery means your system is lightweight and expandable for more assist range as needed. The number of LiGo cells selected for the system will determine the maximum power and range of the retrofit. Why pay for – and carry more than you really need?

Each LiGo pack is 2.7Ah (610g) and can be combined with additional packs to create a larger capacity battery system. In addition the LiGo battery packs are travel-ready, conforming to FAA passenger aircraft flight regulations.
