AM120

A replacement drive motor for HappyRun's larger electric bikes. A motor that has lost power, started making noise or stopped turning is usually beyond repair, and swapping the unit restores the bike to its original output rather than nursing a failing one along.

Motors differ by model and, on the G70 Pro, by position: that bike is dual drive and the front and rear motors are ordered separately. Pick the option that matches your exact model before ordering, since parts are not shared across the whole HappyRun range. If you are not sure which version you have, send Adventure Motion support a photo of the original part and we will confirm it.

Fitment

  • Models: G60 Pro, G70, G70 Pro (front or rear), G100, G100 Pro and G300 Pro
  • Dual Drive: G70 Pro front and rear motors are sold separately

Note

  • Ratings: HappyRun does not publish wattage figures for these replacement motors. Contact Adventure Motion support if you need the rating for your model before ordering.

  • Direct replacement drive motor
  • Covers G60 Pro through G300 Pro models
  • Separate front and rear options for the dual-motor G70 Pro
  • Restores original power delivery

This part carries a 12-month warranty from the date of delivery against defects in materials and workmanship, in line with HappyRun's published coverage for motors and electrical parts.

The warranty does not cover normal wear and tear, damage from abuse, neglect, misuse or accidents, damage caused by stunt riding or jumping, water ingress, or any self-modification. To start a claim, contact Adventure Motion support with your order number and photos of the issue.

Which models does it fit?
Choose the matching option at checkout. this listing covers g60 pro, g70, g70 pro, g100, g100 pro and g300 pro.
How do i know which version i have?
Send adventure motion support a photo of your existing part along with your bike model and we will confirm the right one before you order.
Does it come with installation instructions?
Fitting is covered in the bike's owner's manual. contact support if you would like the relevant pages sent over.
The g70 pro has two motors. which do i order?
Whichever has failed. the front and rear motors are listed as separate options, so order them individually.
Is professional installation needed?
A motor swap involves the wheel and the wiring harness. it is straightforward for anyone comfortable with bike mechanics, but a bike shop is a reasonable call if you are not.
