ONESPORT OT18 User Manual


WARNING — Safety

Read the entire manual before assembly and first use. Do not modify, disassemble, or replace original electrical components. Any modification voids the warranty and may endanger the rider.

ONESPORT recommends a full check by a local mechanic before the first ride. Water resistance does not mean full immersion: avoid storage or use in prolonged heavy rain.
