Reention Dorado In-Tube Battery
The semi-integrated pack used by Aventon, Ride1Up, and dozens of others. Slides into the downtube for a cleaner look than a bolt-on Shark case.
Safety notes
Only fit UL 2271 / UL 2849 certified replacement packs with genuine name-brand cells. Mismatched or counterfeit packs are the leading cause of e-bike battery fires — when in doubt, buy the pack direct from your bike's manufacturer.
The Dorado is the in-tube battery you'll find on a huge swath of direct-to-consumer e-bikes. It sits partly inside the downtube for a tidier profile and lower center of gravity, with a keyed lock and a slide-in mount. Because so many brands use it, finding a genuine replacement is straightforward.
As with any pack, the case is only half the story — what matters is the cells and BMS inside. Buy the replacement that matches your bike's exact Dorado variant (there are a few mount lengths), and prioritize genuine Samsung/LG cells over capacity bragging numbers.
Where to buy
Two paths — match your spend to the build. Quality picks last longer and come with real support; affordable picks get you rolling for less. Always confirm fitment, voltage, and connectors for your bike first.

Pro tips from our test team
- Check your bike's spec sheet for the exact Dorado model before ordering.
- Genuine replacements from the bike's maker guarantee BMS communication with the display.
- Store at ~50–70% charge if you won't ride for weeks; never store fully drained.
