ONESPORT OT08 Pro – Electric Fat Bike with Two Batteries and 170–190 km of Range

The OT08 Pro takes the solid base of the OT08 — Bafang 500W motor, hydraulic brakes, 4 inch fat tyres — and adds a second 18Ah battery mounted on the rack. Total capacity doubles to 36Ah and range rises to 170–190 km, the highest in the whole Onesport fat bike range.

The extra battery on the rack connects to the bike's electrical system and can be charged separately or at the same time as the frame-integrated battery. That configuration turns the OT08 Pro into a serious option for riders doing long tours without access to a socket, or who want to remove range anxiety entirely.

170–190 km – the longest range in the Onesport fat bike line-up

By doubling battery capacity with a second unit on the rack, the OT08 Pro reaches a range that rivals many premium electric bikes with a single very large battery. The difference here is that you can choose to use one battery for short trips, keeping the second charged in reserve.

The same solid technical base as the OT08

The Bafang 500W motor, hydraulic disc brakes and Kenda fat tyres are identical to the standard OT08. The only functional difference is the extra battery — there is no performance compromise in gaining the extended range.

Note: the weight of the second battery raises total weight slightly compared with the standard OT08, but placing it over the rack keeps the bike balanced.

Who the ONESPORT OT08 Pro Is For

Long Tours Without Access to a Socket

170–190 km of range easily covers multi-day tours with no need to recharge.

Riders Who Want to End Range Anxiety

Two independent batteries give extra security — if one runs flat, the bike carries on with the second.

Commuters Without Daily Charging

A full charge of both batteries can cover two weeks of commuting for many riders.

Frequently Asked Questions about the ONESPORT OT08 Pro

Are the two batteries used at the same time or one after the other?

The system can be configured to use both batteries simultaneously for maximum distance, or one after the other to extend cell life. The option is set from the Onesport app.

Does the rack battery take up luggage space?

Yes, the extra battery occupies the rack, limiting your ability to carry additional luggage in that area. If you also need carrying space, weigh up that trade-off before buying.

How much more does it cost than the standard OT08?

The OT08 Pro is positioned as the premium extended-range version, at a higher price than the standard OT08, justified by the additional 18Ah battery and the doubling of range.

Do both batteries use the same charger?

Yes, both 18Ah batteries use the same charging standard, though they can be charged separately if you have two chargers, or one after the other with a single charger.
