Strengths
- Dual removable batteries totaling 920Wh; Tom's Guide verified roughly 90 miles on pedal assist and 50 on throttle.
- Gates Carbon belt drive, no chain lube, no rust, tens of thousands of miles of life.
- $1,199 against a $2,499 MSRP is one of the deepest verified discounts in the commuter class.
- UL 2849 certified, step-through frame, sold through Best Buy as well as NIU direct.
- Tom's Guide called it the best electric bike for range anxiety.
Weaknesses
- Mechanical disc brakes stopped notably longer than the hydraulic commuter average in testing, the spec's weakest link at 28 mph.
- No suspension anywhere; owners call the ride harsh on broken pavement.
- Single-speed belt means ghost pedaling past about 12 mph and labored steep climbs.
- Only 3 widely-spaced PAS levels; the jumps between them feel abrupt.
- 70.5 lbs is heavy for a commuter, largely due to the second battery.

The BQi-C3 Pro is a 2023-era design being sold at a 2026 clearance price, and that combination is exactly why it belongs in the catalog. NIU, better known for electric scooters, built a commuter around two ideas: never worry about range, and never maintain a drivetrain. Both ideas hold up. The original $2,499 price did not, and the market said so; at the current $1,199, the calculus reverses completely.
The two big ideas
Dual removable 48V batteries total 920Wh, and Tom’s Guide’s testing essentially validated NIU’s claims: about 90 miles in pedal assist, about 50 on throttle alone. That is double the usable range of most $1,200 commuters, and because the packs are separate, you can run one and leave the other charging. The Gates Carbon belt drive is the other headline, no lubrication, no rust, no stretched chains, just a quiet loop that outlasts several chains’ worth of miles. For a leave-it-outside, ride-it-daily commuter, the belt is a genuine ownership upgrade.
What the clearance price reflects
The compromises are real and reviewers documented them consistently. The mechanical disc brakes posted a 21’9” stopping distance in Electric Bike Report’s testing, meaningfully longer than hydraulic-equipped rivals, and the thing we would most want to upgrade on a 28 mph bike. There is no suspension at all, and owners describe the ride as harsh wherever pavement deteriorates; the balloon tires only absorb so much. The single-speed drivetrain ghost-pedals past about 12 mph and makes steep climbs throttle-dependent. And with just three widely spaced assist levels, power delivery feels stepped rather than smooth.
Who should buy it
Flat-city commuters with long routes are the bullseye: the range is unmatched at the price, the belt eliminates maintenance, the step-through frame and Best Buy availability lower every barrier to entry. Riders in hilly terrain, or anyone who prioritizes braking hardware and ride comfort, should put the same $1,200 toward the Lectric XPress 2 or Tenways CGO600 Pro instead. As a pure dollars-per-mile-of-range play, it is close to unmatched at this price.
