This is slightly annoying because other than the tires, everything else is assembled using hex keys (also known as an allen wrench). I would have prefered if the handlebars required Hex keys because you could use a multi-tool to quickly make adjustments while riding without needing any other items, but as it is now I always have to carry an adjustable wrench with me. The wrench built into my multi-tool is made for tires, so it is slightly too large to fit and adjust the handlebars because they used another type of bolt like screw for it. This Shimano bike also has powerful linear pull front and rear brakes, a deluxe padded MTB seat and an alloy quick-release seat clamp for easy height adjustment. Other components include spoked wheels, resin platform pedals, a rear derailleur and a three-piece high-performance crank. The authentic Hyper graphics complete the look and give this 20? boys’ bike a stylish appearance. The Hyper Havoc FS mountain bike is 26? in size, it is a 21 speed mountain bike, with Shimono gear shifters. Before I get into all the cons with the bike, I will first tell about the pros.The most obvious pro is the price, this bike is very cheap and affordable for what you get in the box and for most purposes of daily commutes to the store or to work, it will do perfectly. So far I have owned this bike for close to a month, so I will tell my thoughts about all the pros and cons I have found.The bike is easy to ride as long as you adjust the seat, oil the chain, and keep the bike maintained, you shouldn’t have too many problems with it straight out the box. The best thing for you to do is to go directly to the manufacturer’s website. A tool is set up to find a bike as easily as possible, in a store near you or directly, if this service is available, in your mailbox (if there is enough space of course). The delivery cost for your order is displayed in your online shopping Cart as an estimated delivery cost. The bike gears and peddles are slightly stiff, but I am sure it will loosen up with a bit of oiling and riding. I would recommend this bike if you are on a budget and need basic transportation for getting around because it does the job and serves its purpose. As far as cheap mountain bikes go, overall the Havoc Hyper FS mountain bike isn’t really all that bad. A few problems I found with the bike are as follows-First, I don’t like how the handle bars are designed because you need a wrench to tighten them up and put them on. This cutting-edge equipment provides a great way for riders to travel faster, farther, and more comfortably than ever before. The instructions were not completely helpful for assembling the bike because they were basic and very general, but overall I found it easy to do and I had the entire thing setup in about an hour or so.

While not suitable for intensive riders, too difficult trails and rough terrain, the brand proves to be an excellent value for money for the less demanding, who are just starting out or simply don’t have a need for a high end bike to have fun. It is well assembled (for the most part) and I don’t think the bike will break or disassemble on me while I ride it. It is an aluminum frame and the tag that was attached to the bike says that it can hold about 275 lbs or so. From a bike of this range, the models are really correct for their price.In the general mind, affordable bikes found at Walmart are synonymous with poor quality at low prices, but here I honestly think we are facing an underrated brand. For example, their $600 electric mountain bike may be surprising but it turns out to be efficient and promising.Once again, as in many other cases, you have to identify your needs before buying. Here you have a brand offering honestly priced bikes that will satisfy beginners who want to start.Their BMX bikes, which are at the origin of the company, are of superior quality. Even when we tried contacting both the seller and manufacturer they didn’t want to just ship a part out, they instead wanted us to ship the entire thing back and gives us a whole new bike set. That would have been fine, but we had already assembled most of the mountain bike and we didn’t want to repack the entire thing just to ship it out and get another mountain bike that we would have to reassemble. The 20? Hyper Bike is ideal for boys who are looking for their next adventure. Featuring a dual suspension steel frame and fork, rugged knobby tiers and an easy-to-use, seven-speed twist-grip shifting, it is ready for any surface on or off the road. Little ones are sure to have fun riding in the park or the trails.
