Hiland 27.5 Inch Aluminum Mountain Bike for Adults - 27 Speed, Hydraulic Disc Brakes, Lock-Out Suspension Fork - Available in 3 Sizes for Men & Women | Perfect for Trail Riding, Commuting & Outdoor Adventures

Haven't really ridden it yet, but here's my initial experience and impressions. Notified by Amazon via Email that USPS had a problem delivering my package. Got home later that day and they left a slip saying it was oversized and I'd have to pick it up the next business day. (Saturday turned out to be a business day) Post office apologized for the issue and explained that they have a contract with Amazon to deliver packages under a certain size and weight but Amazon keeps sending them things way outside that limit like oak king sized beds with the mattresses. My bike was just a bit over their delivery size. (No worries it fit in the back of my jeep) So add an extra day and expect to go get it if Amazon uses USPS. Initial impression was that the box was thin for it's size. There was slight damage to the box consistent with what has been shown on other reviews. The weight of the box was nice and light for being as big as it was. (I was starting to get a little excited because of how light it was.) Got it home and opened it up. No excessive packaging, no blocks of styrofoam, just some plastic and foam sheeting, some zip ties, and a couple of plastic disks to protect the ends of the axles. Inside was two kind of generic instruction books. One in german, one in english.General assembly wasn't bad, just been a little bit since I've messed with a bike. Tuning the derailleurs was a little more time consuming. The generic instructions were slightly helpful though the pictures were only moderately close to what is actually on the bike, and I ended up having to change the install angle of the front derailleur and tighten the control cable to get it to work correctly. (Not even hinted at in the instructions.) Centering the front brake was also a bit of a challenge but I got it so it doesn't rub on the disk when the wheel spins. (Again not much help from the instructions) The rear brake wasn't as firm as the front and after a bit of exploration I figured out how to add more fluid. Just a tiny amount of D.O.T. 3 fixed the issue and now both sides are equally responsive. (Absolutely nothing in the instructions on how to do this or what fluid to use) The front shock has a nice lock out feature that keeps it from compressing, and has an adjustment knob on the other side. (Nothing in the instructions on what the adjustment knob is or how it works.) Shocks feel a little weak, even after messing with the adjustment knob, and I suspect that like the brakes they may be low on oil... I'll have to research the shock assembly. A quick trip to get the tires aired up and my bike was ready to go... except for a seat change. I bought an after market seat for it since I was expecting the stock seat to be an unpleasant experience as seems to be the case with most mountain bikes from reviews I've read. Surprisingly the stock seat didn't seam that bad. It had a surprising amount of cushion and flexibility. I might have been okay using that seat. Lastly the kickstand is adjustable (nothing in the instructions on it) Initial test ride wasn't bad. Derailleurs worked well. Brakes were nicely responsive though I just went up and down the street (it's a moderate hill) and made a few laps around the big tree in my yard. It handled the roots and rough ground well, the gearing made for an easy assent up the street. I unlocked the front shock and took it for another spin. Jumped the curb into the yard around the tree a few more times and dropped off the curb into the street (about a 6 inch drop) . The shocks handled it well and I didn't get the sensation I was going to fall forward over the handlebars. (Bad shocks will do that.) So far, I'm happy with it. Total time to assemble, set everything and air up the tires about 1.5 hours. Instructions need to be better, and would really like a good breakdown on the components but I'm an aircraft mechanic and I'm a bit spoiled when it comes to having access to diagrams and specs. The matte black paint looks sharp but picks up and shows oils from your hands like crazy. The manufacturer finish on some of the smaller items shows a lack of quality and is on par with the cheaper stuff from china. Only shipping damage I noted was a small scratch on the left crank arm but realistically that could have been done during assembly. Will update after I take it on the trails, and compare it to the big name $1200+ bikes that my friends ride, I plan to do a complete tear down to examine bearings and other components soon as well. It's been a few weeks, and have yet to ride it on a trail due to weather but have put several road miles on it. The fork lockout works well but with it off the shocks seem a bit weak even when adjusted to max. Contacted customer service trying to get a little information on what type of oil the brakes use and what type of fork I have and if it can be adjusted further. Customer service wanted my order number and a video of the problem. I explained to them it isn't an issue of the bike being broken, that I just wanted servicing information. 4 rounds of emails later they told me mineral oil and take the fork to a bike shop. (They won't give you anything without the order number) Not having better information on what equipment the bike has is frustrating. Eventually brake pads will need to be replaced, and the forks will need some attention. I'd rather do this service myself than take it to a shop and wish them luck on researching parts. Will probably end up replacing those components with aftermarket parts that actually provide service specs and part numbers. Dropping down to 3 stars for customer service being unable to provide me with specifications. Been out on a few trails now. The chain broke first day out, but a master link provided a quick fix. Handles the roots, rocks, hills and drops fairly well. First thing I replaced was the seat. Nothing really wrong with stock, I just wanted a little more cushion for my sensitive parts. Upgraded the tires to 27.5 x 2.3, I don't think a 2.4 will fit. Did a gnarly endo at about 25 mph. Front tire cleared an obstacle but the rear didn't, and the bike and I got some good airtime before the ground interrupted our flight. No damage to the bike, I had a some good bone bruising on my shoulder and collarbone. I was doing some minor adjustments at the house, and took it for a test ride when the rear brake line shot out of the hand lever. Looks like the pressure sleeve (called an olive in bike terms) wasn't properly installed. I'm just glad it didn't happen on a trail when critical failure would have been dangerous. No name or model number on the brakes, so no looking up replacement parts, and after my previous attempts with customer service I just bought a complete name brand replacement set.
