U4 Foldable Step-thru Electric Bike 500W Motor 88km Range

I bought the U4 two weeks ago to go to work (9km each way x day) in London. PROS: 1) The pedal assistant of 3 level really help me in the traffic or with the hills. I’m super happy about it because I can get to work without sweating. And I never used so far the trotter option! 2) Super easy to fold! 3) The computer it’s really visible even during the night! CONS: it’s really really heavy! I have to do 3 flights of stairs everyday (back and forth) and it’s really hell! Also, I will never be able to bring the bike (even folded) in the overground or underground! Only the battery itself I think it’s 5kg 😅 so maybe if you are looking for a light bike you should consider other options. 2) I live uphill so that might effect in my judgement, but there is no way that I’m doing 55miles (88km) with 1 charge! At the end of the day my battery it’s already on 1 and I did only 20km… so probably I would do 30km with the full range! 3) the frame it’s not the best… of course you paid £478 so I’m not complaining! But you can feel that is not strong (specially when you get a bump in the road or when you go fast you really need to have a grip on the handlebar because it might start trembling).
Overall I can’t complain! It’s a good bike for the price you paid!

I have bought a isinwheel Electric Bike for my brother as a birthday gift. It’s fantastic electric bike easy to use and store away. The furthest I have travelled was 22miles and there was still plenty of juice left in the battery, and the seat is very comfortable for me. And is worth of money to buy. Hight recommend it.

Nice e-bike, make my life easier.
A little drawback is the weight, it is quite heavy.

I did have a problem with the bike after a few months of use, I contacted the seller and they were prompted with a response and resolved the issue for me and sent me out a new part within a week. And now up and running.

Would recommend this bike I brought for my partner to go work and back it's perfect for her I have also ride the bike it's pretty fast easy to use small enough so it's not in the way and has been used every day for 5 days before having to recharge. 6 months on we still going strong used every day battery last a little less when freezing which is normal but would recommend this bike.
