MiRider 20 GB3 Geared Belt Drive Foldable Bike

The MiRider 20 GB3 is a compact folding bike built around a magnesium alloy frame, designed to handle urban commuting and short-range journeys where portability matters. The 20-inch wheels keep the folded package genuinely small and manageable, making it practical for combining with public transport or stashing in a flat or office. With just 106 miles on the odometer and purchased at the beginning of 2026, this one is barely run in and in excellent working condition throughout.

The motor is a 250W rear hub unit that reaches a maximum assisted speed of 25 km/h, which is enough to take the strain out of commuting without turning every journey into a full workout. The drivetrain uses a 3-speed hub gear system with belt drive, which is a genuinely low-maintenance setup compared to traditional chain drives. There's no derailleurs to adjust, no chain to clean and oil constantly, and the belt drive itself produces almost no mess. The hydraulic disc brakes give you reliable stopping power in wet conditions, and they feel responsive without being twitchy.

This particular bike comes with everything you'd reasonably need to get going. The battery and charger are included, plus two spare inner tubes, puncture repair kit, gear oil, folding multi-tool, touch-up paint in the original colour, and cleaning solution with brush. That's the kind of package that shows someone's thought about what owners actually need rather than just selling you a bare bike.

The orange colour is distinctive and practical for visibility, while the magnesium alloy frame keeps weight down without sacrificing durability. It's the sort of bike that works well for commuters who need something compact enough to live with them on the train or bus, or for anyone who wants assisted urban riding without the complexity of a full-sized electric bike.
