Fatfish Grime Fat Tyre Electric Bike

Fat tyres and a comfortable ride for everyday trips and longer days out. The Grime is a fat-tyre electric bike with 20-inch by 5-inch tyres for grip and stability, and a fully adjustable rear suspension. Its flat, textured seat and heavy-duty rear rack make it practical for carrying gear.
The 250W rear motor gives pedal assistance with high torque for hills and take-offs. Four-piston hydraulic brakes with 203mm rotors give strong stopping power. Built-in GPS works with the free iReadyGo app to track the bike, send movement alerts and allow remote shut-down.
