Beyond this configuration, our OEM & ODM service covers logo printing, customized packaging, color matching and specification adjustment according to your requirements, so distributors and brand owners can align the bike with their own line-up.

Materials and Structure

The frame is made of 6061 aluminum alloy, a high-strength, corrosion-resistant and deformation-resistant material, and carries a Suntour aluminum alloy suspension fork that buffers impact before it reaches the rider. The wheel set combines 26*2.0 CST tyres with reinforced alloy double wall rims that resist impact and compression under load. Braking is handled by a hydraulic disc brake at the front and at the rear, while the drivetrain runs a SHIMANO 9-speed system with a durable KMC chain.

Applications

As an electric city bike, the DOPHIN suits daily commuting, errands and leisure riding in urban environments, and the 9-speed gearing and suspension fork also cover mixed road conditions and gentle slopes. The platform is supplied to distributors, retailers and brand owners, with the company's main export markets in the EU and USA.
