Tandem bicycles can be viewed as one of the first customized bicycles. The first tandem was created when an inventor welded two bicycles together to create a bicycle for two. By the 1800s the bike design had been patented and marketed. Today's tandem bike designs are more than merely two regular bikes welded together, they are high end custom machines designed for high performance. There are even off-road models available for adventurous biking couples.
There are several terms that you need to learn when talking about a tandem bike. The first is the term used to describe the person riding in the front seat. This person can be called the captain, the steersman or the pilot. The person sitting in the back seat is called the stroker, the rear admiral or the navigator. Some of the parts of the bike that you may want to familiarize yourself with include the cranks, which are the pedals, and the timing chain, which is the chain that connects the two sets of cranks. This chain is important because it forces the two cranks to turn at the same time.
When shopping for tandem bicycles you may want to familiarize yourself with the different types that are on the market today. The first type of tandem is the bicycle tandem. This tandem has two wheels, two seat, two sets of handlebars, two sets of cranks and a single timing chain. The second type of tandem is the tricycle. This type has three wheels and it is designed for two people. Its wheel configuration includes a single front wheel and a pair of wheels in the back. The third type of tandem is the recumbent tandem. This type of tandem has seats that are positioned so that the riders are in a reclined position instead of an upright position.
Tandem bikes are manufactured by several custom bike builders and major bike manufacturers. Bohemian Bicycles in Tuscon, Arizona and Co-Motion Cycles in Eugene, Oregon are two companies that hand build their bicycles. If you are looking for a manufacturer with a larger selection of options then you may want to look at the bikes offered by Trek Bicycles. This company not only manufactures quality tandems, but they have also produced Tour de France bikes for Lance Armstrong and bikes for the Discovery Channel Pro Cycle Team.
Tandem bicycles are the perfect way for couples to exercise together and for families to experience the joy of riding together. Learn about the history of tandem bikes, the terminology that is associated with tandems and the variations that tandems come in. If you are a fan of the classic lowrider car, or if you grew up in the 60s or 70s, then you are going to love lowrider bikes. These fun bicycles offer you the chance to rekindle memories from your childhood and relish the tales of customizing your first bike. Learn how to identify a good deal when shopping for used tandem bicycles. Folding tandem bicycles can come pre-made, or they can be made from retrofitting a regular tandem with a special coupling device.
YAMAHA YZF-R1 Road Test
IT'S easy to become a little jaded in this job. If you're riding bikes constantly, their novelty can wear off a bit. But every so often something comes along and makes you feel like an excited teenager all over again. Yamaha's 2009-spec R1 is one such thing.
It's one of the most anticipated bikes of the year, and with all the hype that surrounds it , boosted hugely by Ben Spies' outstanding early success in World Superbike, I couldn't wait to ride the superbike. Feeling jaded suddenly felt very much a thing of the past!
Seeing the R1 for the first time in the flesh didn't really get my heart racing. It's a decent looking bike for sure, but nothing exactly outstanding. Its aggressive 'face', build quality and general shape are all attractive, but I'm not sure whether there's enough different about it to turn heads. What does set it apart though, and what is debatably the Yamaha's main draw, is its engine.
Fire it up and the unique growl from its pipes is unlike anything else on the market, though it is very similar to the noise made by one of the most famous race bikes out there , Valentino Rossi's M1 racebike. That shouldn't be any surprise really as the R1's 'crossplane' crankshaft has been inspired by the Italian's Grand Prix machine. The uneven firing order it generates is the reason the road bike sounds very similar to his racer. But more importantly, the crank arrangement is also why the R1 delivers its power in the special and very effective way it does.
Most in line four cylinder bikes, even the big capacity ones, have plenty of low down torque. But there's a certain softness to their initial drive at slower engine speeds. Add more revs and that acceleration becomes harder, as the effort of all four pistons combines to deliver their real meat. On this year's R1 though, there's already a noticeably harder edge to the delivery at low revs. Not quite as strong or explosive as a big V-twin's, there's still definitely a tempered version of the immediacy typical of those engines in evidence. It's a sharp, yet friendly pick up that's easily good enough to fire the Yamaha strongly from a standstill, even considering the very tall first gear ratio. And thanks to the civilised manners, you can get on the power earlier and not fret about it. It's a truly superb engine that pulls with just the same useful strength in the rest of the gears. Make no mistake though, even though the motor might sound and feel lazy, it's always capable of making some serious speed.
Along with the distinctive sound and manners, the in line four still has the same rush when you do rev it a lot harder. And when the tacho hits 10,000rpm, suddenly all the lazy, easy-going performance is replaced by a very strong charge so typical of a four cylinder motor. There's a super-thrilling buzz on offer when you cane it this hard, and instantly creates a 'god, I love this bike' feeling. And that's the real beauty. The engine has the lazy, usable punch of a twin and then the manic, 'hang on tight' scream of a four. The R1 might now have the shortest stroke engine in the big sportsbike class, but in no way is it peaky. It's utterly fantastic to sample at all rpm. And if you ever want or need to tame things a little, there's a three-position power mode switch that can alter the pace at which all the potential is delivered. 'A' is very sharp, 'Standard' is how I tried it virtually all the time, and 'B' is softer; useful to the less experienced or in poor weather.
Just as brilliant as the engine, is the Yamaha's chassis which seems to easily cope with all the horsepower the motor makes. Given just how potent it is, all components are expected to do a hell of a lot. But in the same, almost relaxed and highly commendable way the engine produces the goods, the chassis also lets you explore its considerable capabilities without ever generating any panic.
The balance of the frame geometry, weight and its distribution, suspension and brakes is nothing short of superb - as is their capability individually. I took my time on the bike for the first few miles, but little by little its poised and planted feel encouraged me to feed in more and more speed. When I started opening the throttle butterflies with a bit more urgency (something I could witness from the novel digital readout on the dash which shows just how much throttle you're using) my confidence remained totally intact. By now I was starting to think the R1 was easily matching all its hype. And it just got better and better.
Apart from the engine, and the chassis capability generally, the steering is what I think sets this bike apart. Feeling so sharp, precise and direct it feels like you're holding the wheel spindle itself. It seems to track your chosen line in a laser-guided fashion, and though under very hard acceleration over bumpy roads the front end starts to shake slightly (before the speed-sensitive damper quickly calms it) you soon develop complete and utter faith in its ability to steer you exactly where you want to head. Great fork action maintains the solid, almost glue-like feel and after a while you get the impression you'll never lose front end adhesion. Even using the power of the very impressive brakes, which have plenty of feel and progression to match their strength, can't seem to trouble either the front suspension or indeed the rest of the bike.
To be honest I'd like to take the Yamaha out on track before I passed a final verdict on how well it handles, but I've every confidence it'll be a lot better than me. In the meantime I'll remain bowled over by just how special it feels , all of the time.
Even when I got caught in rush hour traffic on London's orbital motorway, the M25, and then in some heavy congestion in and out of Oxford, the bike still continued to impress hugely. I'd expected to find it a bit uncomfortable at slower speeds, with some testers telling me it can feel a bit 'wristy' thanks to its low-slung bars. But though I'm quite sensitive to too much of a 'bum up' stance, I had no worries at all with this bike. And even when I was cruising along a boring stretch of dual-carriageway, I found the fairing and screen offer a lot more protection than expected. It's no tourer, but I'd ended up doing well over two hundred miles on my first day on the Yamaha, and felt no worse for wear at all.
It was during my 30-mile stint on my homeward trip that I found myself most thrilled by this exceptional bike though. With most of the traffic gone and the sun starting to set, howling along a familiar stretch of backroad let me enjoy the highly impressive cocktail of ace engine, brakes and suspension more fully. And because of the noise, reputation, and the downright brilliant performance of this very special bike, the thrill of it all was over far too soon. I actually felt unhappy to arrive home. Clocking up another 600miles in the following days soon got me smiling again though.
It's been a long time since I've been fired up by a bike even before I rode it, and even longer since one satisfied me as much as this superbike did. Only time will tell if it's considered the new king of the crop, but in my book it already is , just like it was when it first came out in 1998. Eleven thousand pounds is a hell of a lot to ask for a motorcycle, but this one is arguably worth even more than that. I think it's a truly exceptional machine, and a lot more than just a brilliant sportsbike.

Bike Problem with Crank Pedal-700C Schwinn commute road bike.?
The crank pedal mechanism appears to have something broken/loose. the pedal unit wobbles up and down in it's housing instead of being steady.
What could the problem be? Looks like either a loose screw or broken bearing/bushing assembly or sthing but I'm not sure...
What do you think??
You stated the 2 problems it may be. Just look closely at the pedal, move it around. Do you see the pedal axle moving? If not the pedal bearings are the problem. You can easily verify this by putting a 15mm wrench on the pedal to check that the axle is tight.
