The MiRiDER 24 is the premium pick in our UK road legal list, a 24 inch step-through folder from a British brand rather than an anonymous import. The listing is plain about its EAPC credentials: a UK road-legal 250W rear hub motor, pedal assistance up to 25 km/h (15.5 mph), and an electric assist type given as pedal assist only. The one extra control is Walk Assist, which helps when you are pushing the bike and is allowed under the rules. That makes it legal on UK roads and cycle paths without registration, tax or insurance.
What the money buys is refinement rather than power. The 10.5Ah (378Wh) battery uses Samsung cells, is removable and lockable, and recharges in around 2.5 to 3 hours, which is quick enough to top up at a desk. MiRiDER quote up to 65 miles per charge, a best-case figure at the lowest assist level, so expect noticeably less on hills or in winter. The 6061 aluminium frame keeps the weight to 21kg, light for an e-bike with wheels this size.
The 24 inch wheels are the reason to choose this over a 16 or 20 inch folder. They roll over potholes and kerbs more calmly and feel closer to a full-size bike, while the low step-through frame makes it easy to get on and off in ordinary clothes. The stem and pedals fold, bringing it down to roughly 86cm high by 30cm wide. That is a slim package for a hallway or car boot, though it is not the tiny cube a small-wheeled folder shrinks to.
LED front, rear and brake lights are built in and run from the main battery, and a backlit LCD shows battery level, ride data and which of the five assist levels you are in. Disc brakes handle the stopping.
Worth knowing before you buy: this is a single-speed bike with no gears to change, which keeps maintenance low but leaves the motor to do the work on steep climbs. The fork and frame are rigid, so comfort comes from the tyres and saddle alone. The Amazon listing is also new, with no customer reviews yet.
