POWER THROUGH ANYTHING,
ANYWHERE
Fat Tires for Stability and Comfort

The BQi Fat Tire 300 floats along on puncture-resistant 26" x 4" tires. Fat tires provide extra traction that helps keep you stable on surfaces that would challenge a regular size tire like snow, sand, or loose gravel. They also provide extra shock absorbtion for rough trails and roads!

Lockable 80mm Front Fork

Front suspension is a life-saver on rugged off-road trails, so we’ve equipped the BQi Fat Tire 300 with 80mm (3.14”) of travel, and made it lockable to save your energy and extend your range on hardpack or asphalt.

Shimano
8 Speed

A gear for charging downhill, and a gear for climbing up with 6 more in between. The world-class Shimano ALTUS 8 Speed derailleur will let you smoothly shift across gears as the terrain changes under you.

Pedal-Assist and Throttle with 4 Power Modes

The right power for any ride. The BQi Fat Tire 300 offers 4 different levels of pedal-assist: No assist, Level 1, Level 2, and Level 3. Use No assist to break a sweat, Level 1 to go the distance, or power up to Level 3 for the maximum boost - the choice is yours!

POWER UP YOUR ADVENTURES
750W Rear Hub Motor

Powered by a brushless 750W rear hub motor with a max power of 1000W, the BQi Fat Tire 300 has all the power you need, no matter the slope or trail.

Advanced Torque Sensor

An advanced torque sensor samples the force of your pedalling 1,000 times per second, ensuring the motor is providing exactly the right amount of power to match. This is a big improvement over the cadence sensor used by most competitor e-bikes which only measure whether or not you are pedalling at all.

Up to 50 Mile Range

With a standard range of 30 to 50 miles, the BQi Fat Tire 300 has all the range you need for a good day’s ride, stored in the partially hidden 768Wh battery.

28mph Top Speed

Reach speeds of up to 28 miles per hour in pedal-assist mode, and up to 20mph with just the thumb throttle. Though sometimes you’ll want to go slower than that so you can appreciate the natural world around you!

UNMATCHED COMFORT & SAFETY
Front and Rear Hydraulic Disc Brakes

When you’re riding, there is nothing more important than your brakes. That’s why we gave the BQi Fat Tire 300 both front and rear hydraulic disc brakes with 180mm rotors.

Colorful, App Connected 3.5” TFT Display

A colorful, 3.5” TFT display shows your speed, range, pedal-assist level, light settings and so much more. Connect to the NIU app via Bluetooth, or plug straight in via USB.

Iconic Halo Headlight

Whether you’re riding through a particularly shady forest, the early morning fog, or are caught out after dark, the Iconic Halo headlight will show you the trail ahead up to 26ft away. Built-in high visibility LED brake lights provide a clear warning to anyone behind when you are about to stop.

Built-in Rear Rack

A rear rack comes standard with the BQi Fat Tire 300, so you can easily carry your camping supplies, groceries, or other gear. Carry up to 66lbs on the rack itself, as part of a total paylod of 308lbs for the entire bike.

5 Bold Colors with 2 Frame Styles

Choose your preferred frame style, then pick the color that best suits you. Both frames fit riders 5’ 8” to 6’ 1”. Your trails await!
