Frequently Asked Questions: E-Bike Parts & Accessories

How do I choose the right replacement battery for my Eunorau e-bike?
Check your bike's model name and voltage (typically 48V or 52V). Choose the matching downtube, rear rack, or seat-tube form factor. For dual-battery setups, use the Eunorau dual battery parallel connector with matching voltage packs.

Are Eunorau cargo trailers compatible with other electric bike brands?
Yes. Eunorau 1-wheel and 2-wheel cargo trailers attach to standard 190mm quick-release skewers or via Eunorau M12/M10 thru-axle hitch adapters, making them widely compatible with most hub-motor and mid-drive electric bicycles.

What is the warranty on Eunorau replacement parts and batteries?
All genuine Eunorau parts, motors, controllers, and lithium batteries purchased through DirtMotoBikes are backed by a comprehensive 1-Year Manufacturer Warranty against defects and include dedicated U.S.-based technical support.

Do replacement hydraulic brake sets come pre-bled?
Yes, Eunorau and Tektro hydraulic brake replacement kits come factory pre-bled with mineral oil and integrated motor-inhibitor cutoff switches for plug-and-play installation.
