Exercise Bike Battery Charging Problems – Charger and Circuit Faults
For self-powered or rechargeable exercise bikes, a failure to charge can be a bad battery, a faulty charging circuit, or a problem with the internal generator.
How Self-Powered Bikes Work
An overview of the internal generator (alternator) and rechargeable battery system that powers commercial-grade, self-powered bikes.
Symptom: Console Won't Power On or Dies Quickly
This indicates the internal battery is not holding a charge. The first step is to replace the battery.
Troubleshooting the Charging Circuit
If a new battery doesn't solve the problem, the issue may be in the charging circuit on the control board or the generator itself.
Diagnosing the Generator (Alternator)
A technician can test the voltage output from the generator while the bike is being pedaled to see if it is producing power.
