Read through these instructions and contact Rad Power Bikes Product Support if you have questions. If you are not confident in your ability to successfully and safely perform all steps, including those critical for safe operation of the bike such as clasp release adjustment, we recommend having the work performed by a local, certified, and reputable bike mechanic.
RadMini Folding Stem Clasp Anatomy:
|1||Release (red button/lever)|
|2||Hex Bolt Set Screw (2.5 mm)|
|3||Hex Bolt (7 mm)|
|5||Roll Pin Set Screw (2 mm)|
To fold the RadMini Stem for storage, press and hold the red stem clasp release and push the stem clasp down. Once the clasp is released, the stem can fold, hinging away from the clasp.
When properly adjusted:
The stem clasp should not release without pressing and holding the red release button/lever.
- When closed and in the locked position (see image below), the stem clasp should not move at all. To test the clasp security, when closed and locked, pull down on the lever without pressing the red release.*
- Once the red release button/lever is pressed, the clasp lever should be so tight, the process of lowering the clasp should require enough resistance that it leaves a depression mark on your thumb.
To properly adjust:
- Use a 2.5 mm Allen wrench to back out the hex bolt set screw part way and a 7 mm wrench to raise the hex bolt approximately one full turn.
- Secure the set screw to hold the hex bolt in place and close the stem clasp.
- Repeat as necessary until the roll pin and hex bolt hold the stem clasp securely.
*If the clasp is not properly secured such that it can be pulled open without pressing the red release button, discontinue use of the bike immediately and contact Rad Power Bikes Product Support as soon as possible.
Before each ride, inspect the handlebar stem for proper alignment, adjustment, and security.
Always ensure the handlebar stem is securely locked before riding or damage to the bike, property, serious injury, and/or death can occur.
Have your work inspected by a certified, reputable bike mechanic in your local area.
