World human powered bike speed records are indeed on recumbent bicycles. But they are very long, flat roads where a rider can move through 60 gears (30 speed chain, and a 3 speed internal hub). They also have larger wind screens. I have ridden both, and just flat cruising the recumbent will be faster, but hills, corners, and stops are the great equalizer. ...

Recumbents can be faster. As was previously mentioned, all of the land speed records for human powered vehicles were set with fully faired recumbents (velomobiles). But what will really make the difference is the rider. Consider this rider you've never heard of, Andy Wilkinson. In 1990 he broke the record for fastest bicycle trip from Lands End to John O'...

Here is my 2c from over 10 years experience in a busy shop: I am assuming that it is the spokes are breaking at the hub. On a drive side wheel, that is where they always break. There is a different rare condition, when the spoke nipples are breaking off at the rim. Rims have two sets of holes, one set on the each side. The spokes might be laced to the ...

Most are set up with one lever that works two brakes at the same time. There are lots of different styles, such as this one for example. You can see that it has 2 ferrules instead of 1, most commonly used on dual disc brakes. There are other models that differ somewhat visually but the idea is the same. Many Trike levers also have a push button locking ...

Commercial recumbent trikes are not like light weight upright diamond frame road bikes. I've been riding high end light weight road bikes for 35 years and have ridden well over 60,000 miles during that time. At 65 I still average 17 mph on my after work 30 mile bike ride. At the start of 2015 I bought a Catrike Expedition and rode the same 30 mile route ...

I would venture to say (and Blam confirmed with his link to the manual) that you have some excessive slack in that chain, and removing it would help. In your first picture, where you're holding the chain, it looks like there is a lateral movement available on what appears to be the axle shaft, to the right. I'd loosen those bolts and try to slide the rear ...

On a upright bicycle you have a part of your weight on your legs part or even most of the time. On a recumbent bike you do not have any part of your weight on your legs. I would say that makes for less tired legs. I have noticed that at the end of a day long ride I keep sitting on my 'bent trike with my feet on the pedals when waiting for our local ferry, ...

If it did not come with a manual you can get one online MERIDIAN OWNER'S MANUAL Page 12 states how to install the secondary chain It states the secondary chain should have less than 5 mm of play up or down

I own a Catrike 700 and also owned a high end upright road bicycle with CF tubular rims, etc. and a Powertap wheel. The Powertap wheel can be mounted on the trike to capture heart rate, wattage, speed, etc. I've ridden the trike over 200 miles and focused on fitting for half that distance (crank length, Q factor, seating position, arm placement, etc.) to ...

These are the Wisconsin State Bicycling Laws: http://www.dot.wisconsin.gov/safety/vehicle/bicycle/docs/bikelaws.pdf 340.01(5) defines a bicycle thusly: "Bicycle" means every vehicle propelled by the feet acting upon pedals and having wheels any 2 of which are not less than 14 inches in diameter. As it makes no mention of where or how the machine was ...

Normally I would say "you wouldn't start from there", but since you have... Since you've managed to add a cassette, I assume you're reasonably confident with tools. You're going to have to make a derailleur hanger that sits in the right place. If you can get a sealed bearing over the axle it'll be easier, but if not you will need to make a plain bearing ...

Answering for completeness: Don't get in this situation and Prevention is better than cure You should have picked up that the brakes were not as good as they were by feel (poor braking) or on visual inspection noticed that the inner cables were starting to fray. Most bikes have two independent brakes. For yours to both fail at the same time is quite ...

Answer: Maybe - speed isn't the problem. While most "limits" have generous tolerances, your manufacturer's warranty could be unusable if there was a structural problem. Your brakes would have to dispel more momentum while stopping, so that will increase wear and runout distances. Riding is a great way to get exercise, and I've successfully ridden road ...

In California a tricycle is a 'bicycle'. For day time operations the only real requirement is that one wheel can skid. 39000. "Bicycle," for the purposes of this division, means any device upon which a person may ride, which is propelled by human power through a system of belts, chains, or gears having either two or three wheels (one of which is at least ...

You do not indicate if this is the SX ("tadpole model" weighing 48 lbs) or the USX HD (weighing 65 lbs.) (Either curb weight is a challenge but if you've been spinning away at 80 or better rpm, I say "reward yourself with a lighter trike." Review the archives at http://www.rtrmag.com - Recumbent and Tandem Rider Magazine or The Recumbent Journal for ...

A small point; but, recumbents were banned from racing with normal bikes early in the twentieth century - they were too fast. I have a homemade tadpole (now retired due to hip problems), I (and my dog) rode it for about 12 years in preference to my normal road bike. It weighs the same as an MTB but is way faster. I rode it almost daily and on many ...

I just purchased a tadpole TerraTrike Tour II Elite and I can't say enough about this particular design, make and model. I made myself keep going today, and was able to do 25.2 miles... my first time on the local bike path. What an exhilarating experience! I ended up at this page as I was curious if riding my tadpole is suppose to be easier than riding a ...

I own a Trice Q and several other bikes... The answer to your question is "it depends". With a 70 km/h wind straight in your face (according to the weather office), the trike will certainly go faster. At least it will go forward. On that particular day I overtook a guy on an electric bicycle. He was the only cyclist going in that direction... 50 km/h wind ...

The bicycle is a deceptively simple machine. The physics behind bicycles is actually quite complex, with multiple forces interacting to produce self-stabilizing behaviour (i.e., ghost ride a regular bike then run along and strike it, the bike will deviate from its current trajectory and self right). For a good rundown of the main physics principles behind ...

The 24" Traditional trikes use the 19" support bar. The 23" versions are for aftermarket longer seat posts. So if that is the original seat post, and your mother is not extremely tall, then you need the 19". The 23" comes into play for taller riders so their knees are not smacking their chin and requires the use of a longer seat post than what comes with ...

To accelerate, the peddler is accelerating the weight of three people plus the bicycle. Once moving, the rolling resistance generally scales with the weight of the total vehicle. the rear wheels and tires have to be sized to carry the weight. The Wikpedia article gives 0.0055 as a typical rolling resistance coefficient for typical BMX tires, which is more ...

I have been in the recumbent business for over 10 years and have not ever heard a technical term to distinguish the pair of wheels versus the single wheel. As there is so little standardization it would be difficult to describe the wheels without ever running into someone misunderstanding. I used to manufacture front wheel drive two wheeled recumbents and ...

As everyone has said, it's true that basic maintenance should keep this situation from ever occurring. So just to be clear, the practical answer is probably have a shop get the front brakes set up properly again for you. But to actually answer the question: Most trikes can't take any kind of rim brake on the rear wheels, so that's out. However, there are a ...

I found out that the trike is a 1975 Free Spirit.

Since it is no load carrying part and if you keep enough clearance between the repaired spot and the tyre there should be no problem. Take care to sand away any rust beforehand and treat the rusted part with rust removing chemicals.

Check out the Atomic Zombie plans for "deltawolf" These are do-it-yourself plans, they don't sell completed bikes. Here's someone's bike from the rear There's nothing to stop you putting the caliper mount further out for a 180 or 203mm rotor. You could also set up the same on the left-hand axle. Note this design is a single driven wheel rather than a ...

Typically, you do not brake all three wheels of a recumbent tadpole trike, but only the front wheels, at least when the trike is in motion. Most high end tadpole recumbents use two brake levers which independently control the brakes on the corresponding front wheel. They may optionally have a third brake on the rear wheel which is used as an emergency or ...

I have a three wheel recumbent with a dual front brake lever which controls both brakes at the same time with equal force, then the left lever is for the rear brake that uses a cantilever brake system. Hard braking I use the all three. My trike is electric and I wasn't going to face down in the road in case I had to stop at 40 mph. This set-up works great ...

Alternatives to adding a (possibly very low) rear derailleur: add a hub gear instead I'm not sure you can do this in-line with the rear axle (it would have to be joined to the hub shell), so it might need to precede the rear axle and drive a second chain. Actually, I see Sturmey Archer make specific tricycle hub gears, but I have no idea how they're ...

I'd guess the single-speed freewheel/freehub on the jackshaft has something wrong with its pawls. That's the bit that lets you coast along without pedalling, and the rear chain will keep moving with the rear wheels. To fix it temporarily you could try flooding the freehub with solvent and wiggle it lots. When its moving better let the solvent dry off, and ...
