  If your Enerwatt Bicycle has a short range, there are several potential causes. First, check the tire pressure and pump up the tire if it's low. Second, ensure the battery is charging adequately; if not, charge the battery or replace the charger. Third, the battery might be damaged or its useful life may have expired, in which case you should replace the battery. Finally, frequent braking, starting, or overloading could also contribute to the issue.
