FAQs
Please read our FAQs page to find out more.
Is the ECO R6 fully assembled upon delivery?
The ECO R6 arrives partially assembled. You’ll need to install parts such as the front wheel, handlebars, seat, pedals, and mudguards. A detailed user manual is included, and you can also watch an assembly video for guidance.
Is it legal to ride the electric bicycle on public roads? Do I need a license plate or insurance?
ECORUSH e-bikes comply with EU standards and are EN 15194 certified, with a speed limit of 25 km/h. They are legal to ride on public roads, and in most cases, no registration or insurance is required. We recommend checking with your local authorities for specific regulations.
Can I ride in the rain?
The ECO R1 has an IP54 water resistance rating, making it suitable for riding in light rain. However, for safety reasons, we don’t recommend riding in heavy rain. Avoid submerging the e-bike in water, as water entry may damage electronic components. When passing through puddles, ensure the water level does not exceed the hub to prevent motor damage. Avoid using high-pressure water to wash the motor and dry the bike promptly after exposure to water.
Can I return or exchange my e-bike through ECORUSH?
Yes, if you purchased your e-bike on ecorush.eu and encounter significant quality issues or defects within 30 days of purchase, you may be eligible for a return or exchange. Please refer to our Return Policy page for more details.
