    Favorite Trail:Twin Rivers!
    Duration Product Used:6 months
    Price Paid: $300.00
    Strengths:Brakes are good
    the gears clicked perfect. NO chain skipping, or Mis-shifts.

    Weaknesses:The shocks are real corny. The front shocks barely absorbs anything. The rear shock is sqweeky. After a couple of months your rear shock MAIN PIVOT bearing will get loose, which means ull be riding and the back of the bike will be wiggling side to side like you have a Severly bent back rim. Rims are single wall so they bend easy.
    Similar Products Used:Specialized 2008 FSR comp.
    Supercycle
    Bike Setup:stock
    Bottom Line:This bike is a cheap bike. I weigh 180lbs and I ride hard. I havent bin able to break the crank or snap the chain. So i guess the drivetrain is probly the best thing on this bike. The shocks are garbage.

    Your better off getting a Hardtail bike for the same price.

    YOU GET WHAT YOU PAY FOR!

    Strengths:the bike has a great frame. Stong 6000 aluminum makes sure it wont crack or break in half. Shimano EZ fire are great shifters, and the derailers are good too although i replaced the back derailer because i bent it off. Front shocks are good for beginers but if you are looking for a downhill and jumping bike this is not what you are looking for.
    Weaknesses:bad back shock, it squeks once you ride it for 5 or so months; i think the bushing is worn. rims are easily bent but for what i do they are pretty good. seat is easyily bent at the clamps. The cranks have factory defects in them i bent one of the cranks just when i was about to start a cat walk.
    Bottom Line:good bike for beginers and light weight kids. but all in all this bike is a a cheaply made bike all except for the frame, shifters, and the derailers.

    Strengths:Strong rims..... Dual Suspension. Rapid shifters
    Good customer service.
    Weaknesses:THE FRAME CRAKED!!!!! I DONT DO DROPS EITHER!! SHOCKS R WAY 2 STIFF!!!!! Cranks fell apart. Rims had metal shavings that shreded the tubes. Rear suspension comes really loose where its bolted to the frame. Shifters arent ajusted right. Stock tires dont last long and have terrible grip.

    Bottom Line:YOU GET WHAT YOU PAY FOR! Dont expect to do anything remotely agressive with this bike. If you want a bike for anything other than easy trails dont buy this bike, you will break it!

    Strengths:It has strong frame, good front suspensions, great derailleurs. I love the look, and my slick shifters.The seat is great excpecially for a rider like myself altough it could be better. The brakes are very rapid and with the suspensions it is very smooth braking
    Weaknesses:the rear shocks are not too great, both of my shocks are noisy. the rims are the worsecause they bend out of place. THe tires are okay until it quickly wears out then you have to buy new or get 3-5 pops a week. There are some problems with the rear derailluer. It likes to skip a lot of gears and after a lot of ride time get noisy. The gears are also bab cause they break a lot.
    Bottom Line:It is a great bike for casual mountain riding without to many big jumps. for beginners it is the best ride. with a few changes such as the tires and rims along with the gears it can withstand a lot . I would change it for aother 300-350 bike.

    Weaknesses:rear coil has no travel. bottoms out on everything. front fork isnt ajustable and is too stiff. (no travel)

    Strengths:All parts look like good, strong frame, smooth suspension, good pedal and drive. But, I like particularly the shifting systeme, Alivio Shimano 24 speeds with EZ shift.
    Weaknesses:Cheap quality rims because they is just simple walled and medium rear tire quality (sometime a lack of grip).
    Similar Products Used:None
    Bike Setup:Alivio Shimano 24 speeds, ProMax V brakes, front RST 281R, rear DNM DV-7, XRims 101, Camel tires. I change the rear tire and rear rim for double walled.
    Bottom Line:Good bike for the price. Good bike for persons who weight less than 160 pounds. Good bike for beginner and weekly riders but, when you become a serious rider, you wont change it for better.

    Purchased At:Second Hand; from bike shop
    Strengths:Price paid was canadian. new: 900$

    Strong Frame, effiicent, rear suspension is an efficent add-on. Good for light trails.

    In need of major upgrades.
    Weaknesses:Dont even bother with the parts that come with the bike.
    salvage the frame and change the front shocks, tires (i recommend a specialized brand), you'll probably also want to change the derailleur to something more efficient like the new Altus or better.
    Similar Products Used:none
    Bike Setup:frame + better components, like manitou mag r front shocks and new derailleur.
    Bottom Line:Good frame, but it should deffinetly be equipped with better components. frame could be a bit lighter. rear suspension is to stiff and should have less strenght.

    Strengths:Great value and good quality. The more knowledgeable and serious riders I know like it very much as well. Its a great bike for the average rider who tears it up on the weekend for a couple of hours.
    Weaknesses:Needs a good tune up after purchase from a bike shop. I put mine together and a lot of stuff was loose after one or two agressive rides. Its good now. Frame style makes mounting on my bike rack a little challenging; if you take off the watter bottle and use some bungie cords-you're off.
    Similar Products Used:none.
    Bike Setup:as sold.
    Bottom Line:Unless you are a serious racer or you just want to have a top of the line bike, this bike will suit most fine.

    Strengths:Excellent mountain bike, it feel great on the route and it is easy to control in the trail. The frame and the components are great but i changed the seat and added mudgards. The frame in aluminium is so strong that when i was on the highway at around 65 miles/hour and that the bike fall from the rack the only damagae was done to the handlebar. I love this bike and it worth more than its price.
    Weaknesses:The only weakness i found its thath the shifters aren't adjusted when you buy it and it is necessary to do it by yourselfl.
    Bottom Line:Good bike that is surprising for its price
    Good for people who do not have a thousand dollars to give for a bike.
    Very very strong components and also of good quality for their price.

    Purchased At:Costco
    Strengths:Great value. This bike has the best components at only Cdn$299. Comes with RST Capa CL front and RST 20B rear shocks, Shimano Acera F/R derailleurs, EF29 shifters, rigid 6000 grade aluminium frame, and Sugino crankset. Although these are things you'd expect on any other "cheap" bike, usually these bikes cost at least Cdn$400. This bike is the best for those who don't have much budget, and it rides as well as many of the brand name duel suspension bikes below Cdn$600.
    Weaknesses:Poor quality control. Although the bikes may all look the same, at a closer look you'll see that many Infinities are either not properly welded or not properly assembled. Also some bikes comes with cheaper, low grade components. Be sure to pick the best one.
    Similar Products Used:Giant Boulder DS. Head Silverado (almost exactly the same as Infinity Quantum, but costs Cdn$499).
    Bike Setup:Stock, same as listed above.
    Bottom Line:Infinity Quantum has a strong frame, and decent components for the price. If your budget is below Cdn$500, it is probably the best duel suspension bike you can buy, if you can find a well built one.
