Besides our kits for biking-triking on less extreme slopes, we are now taking orders for more demanding applications.
Heavy Duty e-Cycle Kit
perfect for cargo and pedi-cab trikes
These "high power" kits include the hub motor, voltage and speed controllers, brake levers with automatic power shuff-off switches, and spokes for your specific wheel size. The kit does not include batteries, charger, or rack mounts. This kit now costs $500...for motor models we stock in inventory, $600 for special order.
