I've owned my Engine Pro for 3.5 years now, and have clocked nearly 600 miles on it. I take it everywhere I go camping, and absolutely love it! Going down hill, I've hit 39 MPH on max power and pedaling on the highest gear, and it still felt stable and fully controllable. The original battery still will take me at least 25 miles on hilly terrain without pedaling at all. After all these miles, I'm still on the original brake pads and discs, original tires, and the same battery it came with. This bike has been a champ on all sorts of environments, from flat asphalt, hilly paved roads, rocky mountain trails, sand, and pretty much everything in between.
The only problem I had when I bought the bike 3.5 years ago was with the charging port on the battery. The retaining nut for the charge port on the battery was stripped out, so the charging port would come out when unplugging the charger. I'm an advanced electronics technician in the aviation industry, so I told them I could repair the battery. After I sent them photos of the defect, they sent me a whole new battery switch/charge endcap assembly. I soldered the new on in and things have been great since then.
After 3.5 years of driving this bike regularly (nearly 600 miles now), there aren't many things that have been concerns, but here they are (and they're minor for me).
*** I left it out in the rain overnight once. Since then, the "-" button for reducing power almost never registers the button press. Most of the time I have to power it off and back on to be able to reduce my power setting. I also cannot enter the menu now, because this button is used to go to the settings menu.
*** The brakes have always squeaked really loud since I got it, but the braking performance is still top-notch.
*** The tires are wearing slowly, even though it's been driven a lot on paved roads. I hit a pothole in the road once, resulting in severe damage to the sidewall of the tire, but the rim held up with no damage. I'll have to replace the tire.
*** The seat is horribly uncomfortable for long rides, so I got a bigger seat off "the big A online store" for a few bucks. I'm not a big guy (5' 8'" at 160 lbs), so the bigger seat wasn't because I was too fat for it. The included seat just sucks. It's hard and puts uncomfortable pressure on the "wedding tackle."
*** After my parents tried my bike, they each ordered one, so they're so good they sell themselves.
*** The aluminum plates in the middle of the frame for the rear suspension has three bolts that go through. These three bolts want to come loose often. A few times a year I have to remove the bolts, lubricate the bushings, and reinstall the bolts with red thread locker (yes, they still come loose with red thread locker).
*** The paint and decals have held up very well. The bike doesn't sit out in the rain, but it's stored outdoors where it gets sunlight daily. The paint hasn't faded, and the decals haven't faded or peeled.
*** This bike has been to the beach a few times, and rinsed off in the hose after to get rid of the salt. A few of the fasteners on the bike have started to get a bit of rust, and the front shocks on the forks are starting to get minor rust of the piston chrome.
I've only folded the bike up for transport a couple times, but every time I've needed to fold it, everything works the way it should. Overall, this bike has been amazing. I received no discount, gift, or incentive to write this review. I just got done riding it on my camping trip I'm currently on, and realized I never gave a review of this amazing bike. I can't recommend it enough. I can't wait for an even higher powered bike to order from them. They are a great company to order your bike from!
If Engwe can sell me a replacement button pad to repair the water damage and a new rear tire, I'd love to hear from them! Thanks, Engwe!
