What our Experts Think  
  • One of Retrospec’s most powerful e-bikes, featuring a 750W motor that delivers strong acceleration and confident hill-climbing performance.
  • Fat 20” x 4” tires + step-through frame provide stability, comfort, and easy mounting for all rider types.
  • Long-range capability (up to ~68 miles) makes it suitable for commuting, errands, and extended recreational rides.
  • Off-road ready comfort system with front suspension (100mm travel) that smooths out rough roads, gravel, and light trails.
  • Full-throttle + multiple pedal assist levels allow flexible riding—ride it like a moped or a traditional bike.
  • Built for versatility, handling city streets, beach paths, and light off-road terrain with ease.
  • Hydraulic-style braking system (model dependent specs) supports controlled stopping power for a heavier fat-tire frame.
  • Step-through design improves accessibility, especially for riders who prefer easier mounting/dismounting or casual riding posture.
  • Integrated battery design (720Wh) keeps weight centralized for better balance and riding stability.
  • Best suited for riders who want power + comfort + rugged capability, rather than a lightweight commuter bike.

Maintenance Tips
  • Maintain correct fat tire pressure for better range, traction, and reduced motor strain.
  • Charge the battery regularly (avoid full drain) and store it indoors in a cool, dry place.
  • Keep electrical components dry; never pressure-wash the motor, display, or battery area.
  • Clean frame and drivetrain after rides, especially off-road or sandy use, to prevent wear.
  • Lubricate the chain and drivetrain frequently to handle higher torque from the motor.
  • Inspect brakes (disc system) often and replace pads when braking feels weak or noisy.
  • Check and tighten bolts, rack, and folding/step-through frame points for safety.
  • Ensure wheel alignment and spoke tension are stable, especially after rough terrain rides.
  • Update or check display settings and electrical connections for consistent performance.
  • Schedule a full e-bike tune-up every 6–12 months for motor, battery, and drivetrain health.
