The Radster Trail is an electric off-road bike with the power to do anything, and the range to go anywhere. The 100 Nm motor makes quick work of hills, the 28 mph top speed promises fast-paced fun, and with two frame sizes for a personalized fit, it’s so comfortable that you’ll barely feel like you’re roughing it.
All Rad ebikes are either UL Certified or tested by ACT to comply with UL 2849.
This means our bikes and electric systems have undergone rigorous testing to meet safety standards set by UL, a respected third-party organization.
Although U.S. guidelines don’t currently require ebikes to meet UL Certification, we go the extra mile to ensure our riders feel safe in the saddle.

Batteries come with a universal key that can be used to lock and unlock the battery to your ebike. Please note that universal keys are not unique to your ebike battery and may work with a variety of locks, including on other Rad ebikes. Universal keys do not offer the highest level of security compared to dedicated or unique key locks. We do not recommend leaving your battery affixed to your ebike in public unattended as it may pose a risk of battery theft.
