Just got a new PARK bike for your little rider? Awesome! Need some help getting it set up? We recommend professional assembly and tune-up from your local bike shop. However, if you’re up for the challenge of assembling the bike yourself, we’ll try help out as best we can.
Tools for Assembly
- 15 mm wrench: used for installing the front wheel (tightening the nuts on wheel axle).
- Note: a pedal wrench is recommended for getting the pedals tight, but a regular 15 mm box wrench might work if it’s narrow enough.
- 13 mm wrench: used to mounting the seat on the seat post.
- 6 mm hex tool: used for stem (front fork) alignment and mounting the handle bars on the stem. 2020 bikes use a 5 mm hex tool for stem adjustment.
- 5 mm hex tool: used for adjustment of brake calipers, pads, and brake cable.
- 4 mm hex tool: used for adjustment of brake lever angle on handlebars. 2020 bikes use a 5 mm hex tool for handlebar angle adjustment.
- 2 mm hex tool: used for adjustment of brake lever reach (small set screw on inside edge of brake levers). 2020 bikes should not require brake lever reach adjustment.

General Tips And Comments
- We recommend tire pressure of 30-40 psi. This does depend on the type of riding your child will be doing.
- Gearing can be changed on PARK bikes. The stock front chainring is a 4-bolt 80 mm BCD sprocket, with varying number of teeth depending on the bike model. The rear flywheel can also be changed out for alternate gearing. Stock gearing on the PARK 16 Pedal Bike is 12/25, for example. Other rollouts can be achieved by changing the front chainring or rear flywheel (calculate rollout on bmxultra.com)
