Rear Suspension Adjustment
The rear suspension of your M2S electric bike is an adjustable, "one-size-fits-most" product. Here are the steps to follow to adjust your rear suspension:
To set up your M2S suspension properly, you will need a bicycle-specific shock pump, which is a high-pressure, low-volume style pump. This product can be purchased from m2sbikes.com or from your local bike shop. DO NOT USE AN AIR COMPRESSOR WHEN ADDING AIR TO YOUR SUSPENSION COMPONENTS.
The process to set sag for your rear shock is to use the o-ring on the shock and your body weight to set 15mm of sag. You can use an open-ended box wrench to measure 15mm.
To add air to the rear shock, you will have to unbolt the top of the shock from the frame to get clearance for the shock pump. A good starting point for pressure is 60% of your body weight.
For coil-sprung rear shocks, tightening or loosening the spring will only affect a small amount of sag on your bike. It is recommended to tighten the collar until the coil is held firmly, then no more than two full turns after.
Coil-sprung rear suspension models have very minor adjustment, and should you need to reduce or add sag, an aftermarket spring will need to be installed. Contact [email protected], and our staff will be happy to assist you with available options.
By following these instructions, you can ensure that your rear suspension is adjusted correctly for your riding comfort and safety. If you have any questions or concerns about the adjustment process, please contact us
