*I added the 5th star after 3 months I have been using the bike. No issues, and value for price deserves the 5th star anyway. Following the original review.* I used my new M50 e-bike for about 100 miles. This e-bike appears to be a very good compromise between an e-mountain-bike and an e-touring-bike. It runs great, despite an initial issue when I received a broken part (the display) in the packaging. The support sent me a replacement part, even if the replacement part shipment and tracking were a bit slow and confusing. This issue is the reason why I gave only 4 stars. In any case I easily replaced the part upon its arrival (and display now works fine showing many important data). The e-bike has full features, with good pedal-assistance and even a throttle. Brakes are with mechanical discs, efficient in my touring use. Assembling the bike was easy, but you could need a second person for the weight and for best front wheel adjustment (including brake). All the operations do not need special mechanical skills. Pedal-assistance (or throttle) has 5 levels (“speeds”), but you can typically use level 1, getting support when the speed is <10 mph. This is good, because you pedal by yourself at 12/14 mph on road/trail, but “it” pushes you (smoothly) when you slow down due to uphill. In some cases, you can switch to higher assistance-levels (e.g. steep and long uphill). You also have a decent classic 7 speed bicycle gearbox. Battery range, for my use, seems to be around 40 miles. Suspensions are helpful in gravel road. The e-bike is stable even if you pedal fast both in asphalt and gravel because of almost-fat tires and the wide handlebar but, on the other hand, it is a bit heavy and the handling in narrow gaps is not always optimal. The best is if you are around 6 feet tall, +/- a couple of inches. Later I again contacted support for a seat clamp lever issue and seat slipping, receiving again kind support and a replacement part. The issue was solved also using some tricks such anti-slip compound paste for aluminum-carbon and additional hose clamp (maybe installing a dropper post is the best). Bottom line: this is my first e-bike, I wanted to try e-biking, I was attracted by the (very) interesting price, and I fully achieved my goal with this product. I like it, I would buy it again despite the logistic issues (solved), also because I realized the manufacturer is actually committed to support customers. It is impossible now a deep review because e-bike is still almost new, possibly it lacks some “top-quality” or “top-performance” elements, but it really seems returning an exception value – full features - for the price. It is perfect if you are getting into e-biking and you want to enjoy some nature trails, some city bike trails, or short commuting.

I have an e-bike that I use for dirt trails and local commuting, but I want to travel long distance, and so I wanted purchase an upgraded e-bike that would allow me to ride the 50-60 miles to my old neighborhood. The Isinwheel M50 27.5" Extended Range e-bike looked like exactly what I needed, so I picked it up. Assembling the e-bike took about an hour. The instructions are complete and easy to follow, so there was no issue there. I charged up the battery and took it for a test spin around the local neighborhood; everything worked as expected. Then the problem's began... A few days later, I took the e-bike for an extended ride around hilly roads in the area. After about 20 minutes, I happened to be going up hill when pedaling suddenly became hard, so I figured something was amiss. It turns out the meter was flashing 'HOT' and so the motor power cut out to protect it. This happened a couple more times, after which I contacted the vendor about the issue. The vendor was incredibly helpful and understanding in trying to troubleshoot the issue with me. Over the course of several days, we tried various things to try to narrow down the issue to either a faulty part or a design flaw. Unfortunately, we were approaching the end of the Amazon return window and we still had not made enough progress to say for sure the cause of the problem, so I decided to initiate a return on the e-bike. The problem with returning an item like this is that I am responsible for paying to ship the product back. I checked the local UPS rates and it was going to cost me significantly to do so, but I had resigned to pay it since it was still much cheaper than the price of the e-bike itself. However, when I informed the vendor that I would be returning the e-bike, they apologized for their inability to satisfy me and offered to allow me to keep the e-bike, rather than incur the cost of shipping it back. Now *that's* service! I can't say enough good things about the vendor Isinwheel and their commitment to satisfying the customer. Just on that basis, I'll be looking to purchase my next e-bike through them, knowing that they stand behind their products. You can be comfortable in purchasing anything through them and know that they will go above and beyond to see you satisfied. I'll continue to play with the e-bike as I have time, but I highly recommend anything this vendor offers. Great stuff!
