Contact COASTA Support →CT8 is rated for Up to 40 miles per charge under the product's stated test conditions. Real-world range changes with rider weight, terrain, speed, assist level, tire pressure, temperature and riding conditions.
A full charge is listed at approximately 8 hours with 3A charger for this model. Use the supplied charger, charge in a dry and ventilated area, and allow the battery to cool after a demanding ride before charging.
You can encounter normal wet-road conditions, but the bike should not be treated as waterproof. Avoid deep water, submerging electrical components and pressure washing. Dry the bike and charging connections before plugging it in, and follow the wet-weather guidance in the owner manual.
Battery removal configuration should be confirmed from this model's owner manual or product documentation. The listed battery specification is 52V 25Ah.
Your bike arrives mostly assembled. Complete the final setup using the supplied guide, then check the brakes, tire pressure, controls and critical fasteners before the first ride. If you are unsure about a safety-critical adjustment, have it checked by a qualified bicycle technician.
Warranty coverage, eligibility and claim instructions are available in the COASTA Warranty Policy. For product support or service questions, contact support@coastaebike.com.
