The U4 is a brilliant little e-bike for UK commuters. The motor is smooth and the 25km/h speed is plenty for city riding. The 20-inch fat tyres make the ride so comfortable on the rough UK roads. The folding is quick and it's light enough to carry onto the train. The battery lasts me about 3 days of commuting. The step-through frame is really practical. Highly recommended for UK commuters.

I've been commuting 22km each way for two months. The battery still has 40‑50% left after the round trip – I only charge every 3 days. The 32km/h assist is smooth and quiet. The 16×2.15 tyres are verrrry plush – they soak up potholes like a sofa. I did a range test once: 92km on eco mode before the battery gave up. That's beyond the claim. The bike feels solid, no rattles. The throttle is handy for starting. If you want long distance, this is it.

The 16×2.15 tyres are massive for a compact bike. I ride over cobblestones and tree roots without flinching. The 32km/h speed is perfect for city traffic. The battery lasts forever – I get about 85km on level 2 assist. The 500W motor climbs hills without slowing. The bike is quiet and the folding? No, it's a full frame but very compact. Love the fat tyre look too.

I use the thumb throttle a lot when I'm lazy. It pulls smoothly to 32km/h and the fat tyres grip perfectly. The range with full throttle is still about 65km, which is insane. The 10.4Ah battery is a beast. I've done 70km rides without worrying. The bike is comfortable, the saddle is okay, and the display is easy to read. Very happy.

I live in a very steep area. This 500W motor pulls me up 12% grades at 25km/h with assist level 5. The battery doesn't sag – still gives me about 75km range in hilly terrain. The 16×2.15 tyres provide amazing traction on wet leaves and loose gravel. The bike feels planted. I've recommended it to three neighbours who also have hills.

I ride 15km each way through mixed city and park paths. The 32km/h limit is ideal – fast enough to keep up with traffic but legal. The battery does three full round trips before I need to charge. That's 90km+ easily. The fat tyres make the ride so smooth I don't feel the broken asphalt. The bike is well built, no creaks after 600km. Highly recommend.

I bought this specifically for long weekend rides. I've done several 80km+ trips without charging. The 10.4Ah battery is a beast. The 32km/h speed is perfect for bike paths. The 16×2.15 tyres are comfortable for hours. The bike feels sturdy and the motor is quiet. No range anxiety anymore.

I do food delivery in Berlin. The range covers a full 8‑hour shift (about 70km) easily. The 32km/h helps me beat delivery times. The fat tyres handle cobblestones and tram tracks without issues. The bike has been reliable for 3 months – only routine maintenance. The throttle is great for quick starts.

The wide 16×2.15 tyres make the bike feel like it's on rails. At 32km/h, no wobble at all. The steering is responsive but not twitchy. The brakes are strong – disc brakes stop me quickly even in the wet. The battery range is ridiculous – I charge once a week for my daily 12km commute.

The 500W motor is whisper quiet. The fat tyres absorb all vibration. I can ride for 2 hours without fatigue. The 32km/h assist is linear and natural. The battery indicator is accurate – no sudden drops. I've put 400km on it, no issues. Highly recommend for anyone who values comfort.

The frame is solid, the paint is thick, the welds are clean. The 16×2.15 tyres are from a good brand. The battery is securely mounted. After 800km, nothing rattles. The 500W motor still pulls like day one. The range is still 85km+. Very impressed with the quality.

I compared this to other long‑range e‑bikes. The U4 has the best battery capacity for the size, and the fat tyres are a bonus. The 32km/h is the legal sweet spot. The motor is strong. No regrets – it's a steal.

Sometimes I just use the throttle like a scooter. The 32km/h throttle‑only speed is plenty. The fat tyres grip well even when accelerating hard. The battery lasts about 65km with pure throttle, which is still impressive. The bike is also comfortable to pedal normally. Versatile.

I ride on a mix of paved roads and gravel paths. The 16×2.15 tyres are perfect – not too knobby but enough bite. The 500W motor handles loose climbs. The bike is stable and fun. The range on gravel is still about 75km. Very capable.

The bike came 95% assembled. I attached the pedals and adjusted the seat. Took 10 minutes. The tools were included. The battery was 60% charged – enough for a test ride. The 16×2.15 tyres were properly inflated. Great first impression.
