Engwe (the company) review - What are they really like? & Engwe Engine X pre - review 

I've had my engine x since October last year. I've done a lot of work on it to put right some if the things engwe should have addressed at the factory. Things like the axle bolts which on mine were too short so I replaced them with some 86mm stainless bolts. Another thing too is the fact the mid suspension has no bushings which means you have steel bolts going through an aluminium frame. Over time this wear will cause a loose back end. I've replaced the metal mudguards for plastic ones as they don't rust and break and cause the rider to crash as it gets jammed in the wheel. The mechanical brakes are adequate but I've replaced the front rotor for a 203mm one with the right adapter for the caliper. Opening and closing the frame can wear out the pins on the battery and they can get hot and melt. The tyres are quite thin and so make a fair amount of noise on the road. I have the revised model where they extended the brace that goes from the seat post to the folding hinge. On the early models it only went 3/4 length which made that part of the frame weak. There have been a number of photos of broken frames. On the revised models they also extended the weld underneath so it to goes all the way to the folding hinge. All that being said it's a good comfy bike. Now I've addressed all the issues I then added a second battery on the rack and run both batteries using a balancer kit. 13ah+10ah. I get about 55 miles. I also have the bmx bars, a 56 tooth crankset and a huge saddle. Also have a power analyser too which recorded 960w peak at about 19amps.
