With a powerful motor, an extended 40+ mile range, and intuitive control features, it delivers a smooth, effortless ride—whether you're navigating daily commutes, running errands, or exploring weekend trails.

Powerful & Responsive Riding Experience
Equipped with a robust 400W nominal (748W peak) brushless hub motor, the GT300 reaches speeds up to 22 MPH and confidently climbs hills up to 20° grade. This responsive motor offers ample torque for a dynamic riding experience, combining power and efficiency in a compact, reliable system.

The front suspension fork absorbs shocks from uneven surfaces, while 26" x 1.95" all-terrain tires provide reliable grip.

Many e-bikes are too small for tall people. The GT300 is recommended for riders up to 6’5". I am 6’3" and the fit is perfect. The seat goes high enough for full leg extension. The 26" wheels feel stable at speed. The 7-speed Shimano gears give me good control on hills. The smart card key is a nice touch. Highly recommend for tall adults.

I commute 8 miles each way on paved roads and bike paths. The GT300 gets me to work in about 25 minutes. The 26" wheels roll over potholes well. The front suspension fork absorbs bumps. The 40-mile range means I charge every 2 days. The bike looks like a normal mountain bike – doesn't scream “electric”. Perfect for adults who want a low-profile e-bike.

I use throttle-only for quick trips to the store, pedal assist for longer rides, and manual mode for exercise. The 5 levels of pedal assist let me control how much work I do. The 400W motor is quiet and smooth. The mechanical disc brakes stop well even on downhill sections. The high-carbon steel frame feels solid – bike weighs 58 lbs. Good value for the price.

I love the keyless ignition. Just tap the card to start. The 36V 10Ah battery is removable and has a smart lock system. I charge it at my desk at work. The 22 mph top speed is plenty for commuting. The 7-speed Shimano gears shift smoothly. The LCD display shows speed, battery, and assist level clearly. Very user-friendly e-bike for adults.

I took this GT300 on light mountain trails near Boulder. Using pedal assist level 2-3, I rode 38 miles before the battery got low. The 400W motor (748W peak) climbs 20-degree hills surprisingly well. The 26" x 1.95" tires grip gravel and hard-packed dirt nicely. The front suspension fork and shock-absorbing seat post make the ride comfortable. Great budget e-mountain bike for adults.
