In-frame Mount

Motor mount that installs inside the frame, ideal when there's room within the frame and you need greater ground clearance.

With a second mount, you can move the Lightest system from one bike to another in about five minutes, without removing the bottom bracket.

• You can print the technical drawing at 1:1 scale and check the fit on your frame before mounting.
• Key requirement: the motor sprocket must keep the chain above the chainring.
