JMMD Assembly Guide
Set Up Your JMMD Ride With Confidence
Use this guide to prepare for assembly, find model-specific setup help, and complete a quick check before supervised riding.
Assembly basics
- Start with the right model. S900, A7, B56, and B31 have different setup paths.
- Follow the manual. Do not skip locking points or mode-specific steps.
- Check before riding. Inspect the ride before every supervised use.
Before you start
Prepare the ride, parts, and setup area
A careful setup helps reduce mistakes. Start with the correct model, lay out all parts, and follow the manual step by step.
Choose the correct model
Confirm whether you are assembling S900, A7, B56, or B31 before following any manual or video.
Lay out all parts
Check the frame, wheels, handlebar, seat, pedals, parent handle, canopy, and small hardware before assembly.
Follow the manual step by step
Do not skip locking points, screws, or mode-specific setup steps.
Inspect before riding
Check the handlebar, wheels, seat, pedals, brakes or footrests, and parent-control parts before supervised use.
Model-specific help
Find assembly help by model
Use the product page for model details while the dedicated manuals and videos page is being prepared.
Final check
Check before every ride
Assembly is only the first step. Before each ride, make sure all parts are secure, the child fits the selected mode, and an adult supervises the ride.
Handlebar is secure
Confirm the handlebar is installed correctly and does not feel loose before riding.
Seat is locked in place
Check that the seat is stable and adjusted for the selected riding mode.
Wheels are attached correctly
Inspect the front and rear wheels before the child rides.
Pedals or footrests match the mode
Make sure pedals, footrests, or ground contact match the mode you are using.
Parent-control parts are secure
If installed, check the parent handle, canopy, guardrail, and control parts before use.
Child is supervised
An adult should supervise children during every ride.
