i would be very interested to see how this thing steers, having a 13 pound (at least) powered front wheel - especially considering the fact that products like this are usually marketed to cycling neophytes who are looking for a way to get out of pedaling

Interesting 'Invention' I remember though my grandfather telling me about something he fitted to his bicycle front wheel in the 1930's. Called the 'Roving Wheel' it was a 25cc single cylinder engine mounted within the wheel adn provided about 25mph at >100mpg. Strange how ideas keep coming around. He did say one other thing, because of the greater width of the Roving Wheel you had to splay the front forks which if you were not careful could weeken the frame welds. What followed if you hit a pot-hole in this condition he describes as "arse over tit boy! Arse Over Tit".

A way to "keep the car" while you bicycle? This is the ultimate self-defeating device for anyone who cares about the environment. Strap a dirty 2-stroke motor on a regular bike and you can produce as much smog riding the bike as a normal 4-stroke scooter does. At least a scooter affords some crash protection- with the over balanced front wheel and a quart of gas on board you are ready to be your own emergency flare the first time you get hit by a car or doored. Isn't there enough obesity in America already without trying to make bicycles effort free?

Do people around here always comment without knowing the first thing about the topic? Christopher, I take it you've never done any bicycle touring before, where lowrider front panniers (centered around the wheel axle) have been used for decades. They don't seriously affect the handling of a bicycle. It'd be more of a problem if the engine was mounted above the wheel, as previous designs did. Steve, don't parrot the usual "4-stroke good, 2-stroke bad" line. And what is a "normal 4-stroke scooter"? Are you aware that all 50cc scooters are 2-stroke because 4-stroke motors of that size are ridiculously weak? Newer 2-strokes have to meet stringent EPA regulations, so don't assume you know everything just because your 20 year old lawnmower smokes like crazy. A quart of gas onboard is bad? Then what does it make a scooter with a couple of gallons? And bicycle campers have been carrying camp stove fuel bottles for ages without any stories of them going up in flames. I guess you didn't watch that episode of Mythbusters which showed how difficult it was to get a gas tank to go up in flames.

Looks to be a pretty cool concept I have a 15 mile commute and was thinking about riding my bike this summer but was worried about the return leg in the evening. something like this just might give me the help i need to make it both ways without being to worn out. i look forward to actual product review when this device comes out next summer. md

Anyone in London, whose everyday mode of transportation is cycling would appreciate the introduction of this kind of wheel- a big relief.the working concept is cool, as you could disengage the motor at will. i'm really looking forward to how the issue of its durability would be tackled since the front wheel is the most vulnerable part of the bicycle(at least from my experience!).if not durable, coughing out $400(approx.£250) replacement cost excluding workmanship cost each time the wheel is damaged would defeat the overall economic running of a bicycle. the designer of the revowheel should also put more resources at making it lightweight, while not reducing its optimal strength.

the optimum idea wouild first be to locate the engine in the middle of the bicycle, providing an even center of gravity...the front wheel is just not practical..nor a blast to ride.

Steve, not everyone lives in Flatland USA. Many people live near hills that leave them not even considering anything but a car to get up them. Within 500 feet of my house is a hill that, if you coast downhill on a bicycle without pedaling, can bring you to a speed topping 40 mph. Care to guess how easy it is to go up? If this thing helps people who wouldn't even consider it get out of their cars, and unlike most bike motors, would not interfere with rear panniers, then you've got yourself a DIY scooter with room for groceries. And you can still pedal it to help it along, getting the exercise you're so concerned about.

Navigator Grig says all 50cc scooters are 2 stroke. That is not the case. It is true that the 4 stroke engines are less powerful than a 2 stroke of the same displacement, but Tank, Geely and several other companies are now seling 49cc 4 stroke scooters that get a top speed of about 30 mph depending on load. However, Navigor is right that the old idea that all 2 stroke motors are dirty is outdated. I think this product is a great idea. Lots of folks use electric hub motors, on the front wheel, with similar performance characteristics. This should work similarly and be substantally lighter (with the battery pack a 24 volt hum motor kit adds about 45 pounds to the bike) It will also be able to make multiple trips without a 4-6 hour recharge.

I was at the company's web site and they do address all the concerns that I see here. It seems that they may have a winning product, if they don't get bought out and the wheel disappears" before getting to the masses. "

to sparalesto the website is https://www.revopower.com If you have time ( lots of it ) Look up Peak oil for some crazy facts about gas prices of the near Future!

Steve, if you read up on the wheel, it already meets emission standards for California, plus the bike is still light enough to pedal, and most 21 speeds can be pedaled faster than 20mph, thus obesity would be your problem, or your boyfriends problem. Also, an experienced and cautious rider provides his own protection, not to mention a helmet and gloves. Maybe you don't like the concept because you can't ride a 2 wheeler. I'm guessing you ride one of the 3 wheeled skooter bugs for geriatrics. Get off the couch, put down the gin, and get some oxygen to your tiny little brain.

I have a friend that rides his bicycle to work every day. He doesn't drive. And it is an 8 mile treck one way alone. I told iwas going to get this product for him to help give him a lttle reprieve from the trek each day. I am even going to get one for myself because of the gas prices. It will be a money saver in the long run.

After a motorcycle accident that pretty much detroyed my left knee I bought an electric bike from the folks at www.zapworld.com, It had about a 12 mile range and allowed pedaling with or without the assist. If you wanted to you could flip a switch and the 'motor' would become a generator for charging the battery.

I HAVE CHECK THIS OUT IT IS A GOOD PROUCT.IT HAS BEEN RESEARCHED BY UNIVERSITY ENGINEERING DEPT. SO HAS GOOD TECHNOLOGY.IT WOULD BEE GOOD IF THEY COULD DEVELOP A WINTER PROOF USE OF THIS.

steve, what can I say. You are an idiot! I've been riding an electic bicycle for years with a 15 lb. motor on the front and 30 lbs of batteries on the back and I have not had one problem with steering OR safety.This motor is a godsend. airhead53cc,excuse me...aircooled53cc, I know how you got your name.I commute 125 miles a week and I am looking forward to having this innovative wheel on my bicycle! No I don't have a car.

I own a two stroke (china) 80cc powered bicycle that goes 30 mph and 200 MPG. It has Worksman heavy duty rims and fat tires to go thru the potholes a horn and a homemade rechargable head light system. I am very happy with it and everyone seems to just love it and all ask where to get one. I had the bike and spent a total of about 250 dollars on the motor kit and extra parts. I have ridden it about 750 miles so far without a problem so you can't say its not a good deal. I figure I should be able to keep it running for many a year with minimal cash and effort on my part. anyhow anyone who thinks there is something wrong with that can poop and fall back in it .... TOM

What's to prevent someone from taking the wheel from your bike? Bike cables are alright, but a good pair of bolt cutters would probably do the trick. U-locks? Special nuts with fancy thread designs? Here at my college, bike theft is very common. If someone is willing to steal a regular pedal powered bike, imagine what they would do to get a motorized one. For $400 something dollars, it's not something I wanna leave to chance. Although, it seems that when buying something like this, you have to accept theft as a given.

Alex, maybe get a 26" folding bike that you can take inside the school or shops. I think the wheel would be a great setup with a bike that folds. You could even carry it in a car.

Yeah, that is a good point Sammi. Although, I'm not sure if they even make folding bikes with 26" inch wheels. Link?

As far as that incorrect comment concerning how dirty, polluting to the environment a two-stroke is.... Are you truly that unaware of the great strides that have been made in the last 7-10 yrs in this arena??? Do some cursory research, my friend... Informed education is certainly better than a knee-jerk and incorrect assumption......

i think its great i want one but i cant afford it and steve if people stop driving there cars and start riding there bikes with this wheel there WILL be less pollution

Can the wheel be easily removed allowing to lock bike outside?

Have you tested the Wheel at altitudes higher than Denver? I live in the mountains, and drive a crew cab truck to work. I don't usually need such a large vehicle, especially at my summer job at a nursery 17 miles east of Eagle. I can't pedal home after doing manual labor all day, and I find the Wheel an interesting alternative to consider. The road I prefer to take is highway 6, a two lane highway, but safe to bicycle. Tell me it runs fine at 7-8,000 feet!

I asked yesterday if anyone has used this wheel on a 27" hybrid. I don't want to buy another bike. Have several & would like to try it on my hybrid. Need suggestions for adaptation.

Please keep me informed regarding the where and when I can purchase the wheel.

Hi, i live in Sydney Australia, where can i buy one of these Revopower wheels.Can someone send me some details please? What a top invention!!!

Wow that is pretty creative. However I would be concerned if anything mechanically malfunctioned inside the engine because you would flip and fall hard since its on your front wheel.
I would prefer a rear tire setup like the motorized bicycles from www.savegasmoney17.com

I just saw this, but looks like most comments were made ages ago and the official web-page does not work.
Is there a place where one can buy this??
I live in Greece by the way...

i think its great. i want one. web site does not exist. please tell me how i can purchase one

What an absolute load of bs, this is not a new concept I saw an 80 or so year old version of this at my local motorbike shop which actually got into production.

We need to understand the difference between a viable product and some kind of students design, before we go running off at the mouth.

How do you stop moving when need to stop ..I have been told that killing the engine is only way too stop motor from moving forward..web site is in active is this due to company is closed .. The web site is no working eather way.. please reply with a working phone number also..thanks

Fake! Don't waste your time!

Revopower wheel,Whats up,Did they go out.
