Suspension Setup

REAR SHOCK SET UP

Recommended Sag = 30%/19.5mm

Step 1: Check the coil rate chart. If you are close to the correct rate, go to step two, otherwise swap the spring for one with the correct rate (not provided).

Step 2: Sit on the bike and note the sag. On a RockShox-equipped bike, this can be seen on the shock shaft. You will likely need someone to help you.

Step 3: If sag is less than 30%, back off the preload ring on the spring one turn at at time. If sag is more than 30%, increase the preload on the spring. (Note: Never preload coil more than 5 turns).

Step 4: Adjust rebound setting to ensure proper control.

For additional information on the setup of RockShox coil shocks, visit SRAM's suspension setup and tuning guide.

FORK SET UP

Marin recommends that all bikes front and rear suspension feel balanced

Step 1: After rear sag is set follow the recommended pressure from the fork manufacture.

Step 2: Bounce evenly up and down on the bike, cycling the suspension up and down to make sure both front and rear suspension feel balanced, if the front does not match the rear add or release pressure.

Step 3: Once the bike feels balanced adjust the rebound damping to ensure proper control.

Reviews

A brilliantly fun ebike from Marin that is built to shred trails and downhill.

Motorised radness on a budget.

This is way too fun!
