Amazon com Bicycle Buying Guide Finding the Right Bike To really enjoy cycling it s important to find a bicycle that works for you Here are some things to keep in mind when you re in the market for a new bike The Right Ride In general bikes are broken down into three major categories Road and Racing Bikes As a general rule road and racing are built for speed and longer distances on paved surfaces Thinner tires lightweight 29 inch 700c wheels and drop bars that allow for a more aerodynamic position are the norm Most road bikes regardless of price offer many gears for tackling both hilly and flat terrain Mountain Bikes With their larger tires hill friendly gearing and upright position mountain bikes are very popular for all types of riding both on pavement and off Mountain bikes that are designed specifically for rugged trail use typically feature a suspension fork Some may have rear suspension as well A quick change of the tires on any mountain bike even one that you use regularly on trails adds to its versatility and makes it a worthy street machine Comfort Cruiser Bikes For tooling around on bike paths light trails or for cruising a quiet beach side lane comfort cruiser bikes are the ticket With a super relaxed riding position padded seats and limited or no gearing these bikes are made for enjoying the scenery and having fun with the family The Right Price A bike s price boils down to three essentials frame materials bike weight and component quality and durability Entry level You ll find a wide range of comfort and cruiser bikes in this category as well as some lower end mountain bikes and road bikes Most will have steel frames and components that are designed to last for several years with frequent use Mid range Bikes in this range may feature a lighter aluminum frame with mid range components that keep performing after miles of use If you re looking for a quality bike that is relatively lightweight and will stand up to abuse this is the sweet spot Most serious commuter and touring bikes fall into this category as do mid range mountain bikes with a decent front suspension High end Racers and serious enthusiasts who expect lightweight high performance components will want to stick to this category For road bikes exotic frame materials carbon fiber titanium and ultra lightweight components can add thousands to the price tag Mountain bikes in this class often feature advanced front and rear suspension technology as well as components designed to handle lots of rugged trail action The Right Size Fit is crucial for comfort control and proper power and endurance on a bike Here are some basic bike fit tips Stand over Height To find out if a bike s overall height fits your body measure your inseam Next determine how much clearance you ll need between your crotch and the top tube of the bike For a mountain bike you ll want three to five inches of clearance A road bike should offer between one and two inches of clearance while a commuter bike should have two to four inches Compare the stand over height for a given bike to your measurements inseam clearance to determine the right bike height Top Tube Length You can measure your torso to get a good estimate of proper top tube length First make a fist and extend your arm Measure from the center of your fist to the end of your collarbone the part that intersects your shoulder Next measure your torso by placing a book against your crotch with the spine facing up Measure from the spine to the bottom of your throat the spot between your collarbones Finally add the two measurements arm length torso length divide the number in half and subtract six inches This is your approximate top tube length Compare this number to a bike s posted top tube length You can allow for about two inches longer or shorter as most bikes can be adjusted via stem length height and saddle fore aft position to make fine adjustments to the fit Bikes for Women Proportionally women tend to have a shorter torso and longer legs than men Bike makers design women s bikes that offer a shorter top tube and many comfort cruiser bikes built for women may also provide more stand over clearance The Right Accessories When you make a bike purchase don t forget these crucial add ons Helmet this is a must Seat pack Lock Hydration pack or water bottles and bottle cages Spare tubes Portable bike pump Gloves Review Summary Good Mountain Bike Bargain at 150 Date of Review: 2007-02-21 | Rating: 5 This is a good bike the best feature is the dual suspension Light and easy dropping off curbs on the way to work huge difference from my hardtail mountain bike Disc brakes are nice to have on front and rear work much better than rim brakes To adjust them hold the brake lever in and tighten them down via a hex wrench on the opposite center of the disc brake until the pads are flush against the disc then turn back until the brake lever has enough play in it The rims are v shaped and narrow much more so than my other bikes It was quite a job to add tuffy liners to to the tires I think I will have a bike shop change the tire next time they need it The hard part is getting the tire off and on those narrow rims The people at REI said to squeeze on the sides of the tire as you put it on so both ends go deep into the rim Be careful when you put the front tire on that you have the fork facing forward I had it backwards the first time Make sure the big round points on U part of the fork point towards the front of the bike The tires are very knobby If you ride on the street a lot you might want to change them to something with a smoother tread in the middle The bike weighs 38 pounds put together not exactly light but since I ride for pleasure and exercise and don t plan to race the weight is fine If you get it for less than 150 what Amazon is selling it for the week of Feb 20 it is quite a bargain disc brakes by themselves often add 100 to a bike I raised the seat pretty high for a comfortable ride at my height and found the handlebars are two low I fixed this by adding some handlebar extenders which allow me to be more upright when I am not braking To my knowledge you can t raise the stem on the handlebars without adding a spacer If anyone finds out otherwise please comment to this post Another possibility besides handlebar extensions would be to replace the handlebar with one that has more of a rise to it The Topkick is made by Kent Bicycle Company for GMC They also make some Cadillac Mountain Bikes the Cadillac AM2 4 and AM2 7 which are sold on Amazon They are both dual suspension with disc brakes and have a very similar frame as the Topkick Both bikes sale for over 1000 Great Date of Review: 2007-02-07 | Rating: 5 This is a great bike However the shipping dented the chain and it costed me 40 dollars to get it repaired new one I called amazon and they gave me a refund for the money i had spent in no time I have to say amazon customer support is great at least off holiday season Great bike needs instructions Date of Review: 2007-03-21 | Rating: 5 First off I ordered this bike from Amazon at 150 on March 5th and was told 4 6 week delivery at mid April being the estimated ship date Luckily I got it by March 20th assembled it and just took it out for a test ride Overall I am very satisfied it is a very solid bike worth every penny As previous reviewers have mentioned shipping quality isn t astounding but it doesn t seem like I have any damaged parts other than slight frame scratches Assembly is quite tedious and the only fault about this bike I could really come up with was the lack of instructions besides the bike being a little bit heavy but it isn t hard to figure out Only tools you need are hex wrenches and pliers Mounting the front brake was confusing and tweaking it to align right was tricky make sure you understand which way to mount and how to tweak before assembling the brake Also make sure you screw the pedals in completely I failed to do so and the pedal snapped out of place while riding although I was able to fix it The dual suspension is really nice to have as well as disk brakes the main reason I opted for this model and quick release tires seat are nice Seat is a little uncomfortable shifting isn t that smooth but both do the job The rear suspension takes up space in the middle I mounted a pump and lock on it but no room for water bottle The kickstand is not your average flimsy stick very sturdy Handle bars aren t the best but adequate Be sure to tighten everything The bike was worth every penny at 150 keep in mind that it came with a claimed 4 6 week wait jumped to 260 as of today I d say if it dropped under 200 get it GMC Mountain Bike is GREAT Date of Review: 2007-01-04 | Rating: 5 I love this bike it s light it looks good it s comfortable it rides amazing it s a great price for what you get I would definitely recommend it to anyone Topkick is topkick Date of Review: 2007-01-09 | Rating: 5 Fabulous bike It appears that they have thought of everything for the rider Don t know about jumping or other extreme sports but for everyday use it s right on Workmanship is defined by the details and this bike has it No sloppy welds anywhere
