Thunder Folding Step-Over F500: Folding Fat-Tire Features

Every figure below is labelled with where it comes from, so a manufacturer’s claim never reads as a measurement.

01 Folding performance

500W Bafang motor with up to 80 N·m torque

The Thunder Folding Step-Over F500 uses a 500W Bafang G060 rear hub motor with up to 80 N·m of torque.

03 Braking and traction

04 Portability

Folding frame for compact storage and transport

The frame folds to approximately 39 × 19 × 28.5 inches, making the F500 easier to store or transport than a full-size fat-tire e-bike.

  • 39 × 19 × 28.5 inFolded size
  • FoldableFrame
  • 20 inWheel format

Folding reduces storage size, not necessarily lifting weight; test the carry if stairs are part of daily use.

05 Drivetrain

Shimano 7-speed gearing for everyday versatility

A Shimano 7-speed drivetrain gives the Folding Step-Over F500 useful mechanical gearing for hills, cruising and lower-assist riding.

  • 7-speedShimano drivetrain
  • Pedal assistElectric support
  • FoldableUse case

Mechanical gear choice remains important for cadence and drivetrain efficiency.

Thunder Folding Step-Over F500 Electric Bike

The Thunder Folding Step-Over F500 combines a folding frame with 20 × 4-inch fat tires, making it a practical option for riders who need compact storage without giving up stable, mixed-surface handling. Its 500W Bafang G060 rear hub motor is rated for up to 80 N·m of torque.

Two Battery Options

Choose a 48V 15Ah or 48V 20Ah Samsung lithium-ion battery. Thunder lists up to 90 km for the 15Ah configuration and up to 125 km for the 20Ah version under favourable conditions. Range will vary with assist level, rider weight, hills, cold weather, wind, tire pressure, and frequent starts.

Folding Step-Over vs. Leisure F500

The Folding Step-Over is the better fit when storage footprint or vehicle transport matters. It also offers more torque and an optional higher-capacity battery than the Leisure F500. The Leisure model is aimed at riders who prefer hydraulic brakes and do not need a folding frame.

Fat-Tire Control in a Smaller Format

Kenda 20 × 4-inch tires and an adjustable MOZO suspension fork help manage cracked pavement, gravel, and everyday road seams. Tektro mechanical disc brakes use 180 mm rotors, and Shimano Tourney 7-speed gearing keeps pedalling familiar across changing terrain.

I drove all the way from Seattle to bring my daughter's scooter to ProMechBC and I could not be more pleased with both the repairs and the customer service. I will definitely be bringing the scooter North of the border when it needs some love.

Recently had an accident with my Apollo Go — luckily nothing major was damaged, but it still needed some repair and replacement parts. Service was great, and I got my scooter back within a week. :D

The service was incredibly fast, professional and efficient — they fixed my scooter wheel quickly and the quality of the repair was outstanding. Honest, reliable, professional and fast.
