If you have a paralysed arm due to a Brachial Plexus Injury (BPI) and ride an adapted trike, there are a few safe and practical options for managing your arm while riding. The most common approach among BPI riders is to tuck the paralysed arm into a pocket, although many find that using a BPI sling inside the jacket is even better. A sling helps to support the shoulder, which can ease some of the pain often associated with BPI.
Because paralysis usually leads to loss of muscle mass and reduced blood flow, the affected arm is also much more sensitive to cold. Keeping the arm inside your jacket helps protect it from wind-chill and maintains comfort on longer rides.
From a legal perspective, you will not be breaking any laws by riding with your arm in a pocket or a sling, provided your trike is properly adapted for safe operation with your functional arm and both feet. While some riders report being stopped by the police out of curiosity or misunderstanding, a polite explanation of your disability and the trike’s adaptations is usually sufficient. If any issues persist, you can refer the officers to the NABD (National Association for Bikers with a Disability), who can help educate them about BPI adaptations.
As for attaching the paralysed arm to the handlebar with Velcro, this is purely a cosmetic choice and offers no functional benefit in cases of complete paralysis. Whether you do so is entirely up to you—it’s not a legal requirement or a safety necessity. What matters most is that you can ride safely and comfortably with your chosen setup.
