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.

Product Perfect - Weak Service Service was indeed weak. Like most of starks customers, im sure i can relate to the stressful, worrying, helpless feelings that starks customer service provided. I waited about 6 months to get my bike and mistakenly relied on thinking i would recieve it in a timely manner. Yet..... it was like everything changed when UPS knocked on my door. Product perfect. Rode smoothly. Yet needed an instruction manual.

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.

Worst company ever. Worst company ever. Now that’s the response I was looking for! Thank you Stark. Keep that up and you’ll see your reviews quickly climb!

This is a GREAT bike This is a GREAT bike, with impressive features - see my unboxing and assembly video. I'm a Cambridge accademic, so I know about cycling, though I'm not a mechanic. It was easy, though there were some surprises. see YouTube pfo7m7rJlN8 There was some damage in transit and I'm having problems getting a response from them about this, but hopefully this will be sorted.
