I would not purchase this bike again.... The bike I received was more or less in-line with the quality one would expect for the price. All told, my 500w version with suspension was around $1,050 US delivered to California. I have two issues with the bike that have resulted in a low rating: 1) When the bike arrived, the brakes were not properly adjusted and the disks are warped. After only two rides, one of the two bolts holding the front brake caliper fell out, it apparently was not properly torqued at the factory. As well, both the front and rear brakes flutter and do not provide linear stopping due to warped brake disks. 2) Pedal assist: after roughly 5 rides on the bike, the pedal assist stopped working at all. The electric motor can only be engaged by using the throttle which I find to be quite annoying. I have physically inspected the crank sensor and it appears to be lined up properly and all the wire connections appear to be solid. I contacted STARK and they told me to take the bike to a local repair shop - at my expense, they only offered to replace any defective parts that the shop may identify. Going forward, I would only buy a bike from an established company that will honor basic warranty requests as this bike is not really usable in its current state. I am heistant to go spend more money to chase down the crank sensor issue since there is no documentation on the cycle computer and I am not sure if it is a setting issue or failure of a component. I am order #684, placed in June 2017 for Batch #2 UPDATE 7/5/18 My review is back on the site after STARK filed a number of false claims with Trustpilot that my review was not legitimate. I included my name and order number with the original review but STARK still went ahead and claimed that I was not indeed a legitimate customer even through they have all the data to verify such. I am by no means a STARK hater and am in fact rooting for STARK's success. But how can a company succeed when they are spending more time and resources trying to muzzle legitimate complaints than focusing on true customer service to ensure the product shipped actually works. I suggest STARK work with customers to repair/address real product failures and the negative reviews will melt away based on the goodwill they engender. Just my suggestion.

sad simply sad The bikes (i ordered two) came via FedEx more then a month past the date i was told to expect them. upon arrival the bikes were damaged from poor packaging and possibly choice of shipper. after getting a chance to ride the bikes i noticed preexisting damage from when the bikes where build. i had other professionals look at the bikes to confirm what i was seeing. i can not find a shop to work on the bikes due to compatibility and availability of parts. the customer service with the company is dismal and the provided information is general in nature much sky of what is needed to maintain my bikes. the company is not willing to inform me of the parts i need and has stopped all communication with me in regards to these two bikes. one of which i have never been able to use the electric component of. very sad maybe my expectations where to high

Really amazing purchase that included a weird error I love the design of the bike and it feels really nice to ride it around my city. Friends that I pass by with the bike gets impressed, and it does indeed feels like a very great purchase! On the other side: When I turned on the electric power, I felt amazed that I cycled so fast that I almost got scared. But for some reason the electricity kinda stopped working on the first day riding out of nowhere. It probably isn't the company's fault but one of the manufacturers, and it feels kinda complex to ask the company for a fix, so I might go to a third party to check this up.

Very unprofessional Everything was going good until Stark drive and UPS delivered to my old address, where the bike was taken by someone. Stark drives "customer support" is a complete joke. I was in contact with them through several emails, in which I was respectful with each one. Long story short, after they basically told me I'm screwed, they stopped replying to me completely. Very, very unprofessional in my honest opinion. Update: It now seems they are trying to start a lawsuit against me for giving this review. 10/30/18 Update: It seems they have gotten new customer service, although it seems they are motivated by my bad review more than anything. I have finally recieved my bike. I haven't been on it yet but it looks nice. It did not come with instructions so I was left to figure it out myself. I'm writing this review before riding it because Stark drive is pushing me to change my review "since I have received my bike". I'm glad I now have my bike, but getting a bike with Stark drive seems like a gamble. You might be very happy with your experience, or you might have one like mine.

This might be the biggest con out… This might be the biggest con out there. They shipped me a “stock” bike 4 months later. Then it was a different bike than what I ordered. They told me I could ship it back but I had to pay for shipping. Then there were missing parts that have still yet to show up 5 months later. No bike shop will touch these bikes. They will blame you for everything wrong. They stole my money.
