The D77 Electric Fat Tire Bike is built for commuting and recreational riding on mixed terrain. It features a 500W brushless rear hub motor (1000W peak) with a top assisted speed of 28 MPH and a detachable 48V 15.6Ah lithium battery that provides up to 50 miles of range in pedal-assist mode. The bike includes a high carbon steel frame, dual suspension, and 16" × 4.0" fat tires to support stable riding on pavement, gravel, sand, and wet conditions. Front and rear mechanical disc brakes, an LCD display, full fenders, and a headlight are included for added convenience and visibility. With a 57-lb net weight and a 175-lb load capacity, the D77 is recommended for riders under 6 ft and is suitable for daily travel and light off-road use.
- Compact 16" Fat-Tire Design for Smaller Riders The D77 features a compact frame with 16" × 4.0" fat tires, making it easier to handle for teenagers and riders with smaller body sizes. It provides stable traction on paved roads and light off-road paths while maintaining a manageable overall bike size.
- 500W Motor with Adjustable Power Assist Equipped with a 500W brushless rear hub motor (1000W peak setting), the bike offers multiple assist levels suitable for different riding preferences. Riders can choose lower assist levels for relaxed control or higher assistance for easier starts and hill support.
- Comfortable Dual Suspension for Daily Use The dual suspension system and padded saddle are designed to help reduce bumps during everyday rides. This setup supports a smoother experience for lighter riders and makes the bike suitable for school commuting, neighborhood riding, and weekend use.
- User-Friendly LCD Display & Practical Accessories The LCD screen shows speed, battery level, assist setting, and trip distance in a clear format. The bike includes full fenders, a headlight, a bell, and a kickstand, offering convenient daily-use features commonly preferred by younger and female riders.
- Lightweight Build with Easy Setup Weighing approximately 57 lbs and sized for riders under 6 ft, the D77 is easier to maneuver and store compared to larger e-bikes. The bike arrives about 95% pre-assembled with tools included, and the main components—battery, motor, and controller—are covered by a 12-month limited warranty.

The must do service package. This is a "fits multiple" kit so youll have some extras. The kit also includes the lower unit gear oil seals, which is awesome. I always trust quicksilver to be durable and a great value for the money.
