Electric Bike Conversion Kits
QUESTIONS? Call 503-719-7678 or EMAIL US

Do you have a bike you find particularly comfortable or satisfying that you want to convert to include electric assist?
Cynergy can convert your regular bike to an e-bike.

Conversion kits are available for:
  • standard bicycles
  • cargo bikes
  • recumbents and tandems
  • adult upright tricycles

We’ll help match the right kit for your riding requirements, your bike and your budget. Call 503-719-7678 or EMAIL US

We need to review any bike we are to install a kit on before we take your order so that we are certain that the kit will be compatible with your bike. Please be prepared to either bring in your bike for review, provide pictures, or provide your bike's make and model.

Mid-Drive Kits - E-Rad from Lectric Cycles

Our best selling kit. Excellent performance. Very smooth and extremely quiet. 350W – 750W mid-drive motor with shift detection*

  • Lockable lithium ion battery
  • 5 levels of pedal assist, plus “no assist”
  • LCD display
  • Right-side/Left-side twist or thumb throttle
