Motorized Bicycle Kit I bought one of these kits and a 44 cc two stroke engine to drive a mountain bike I have. The other kits I see are weak on engineering and require too many mods to the bike. This is super simple and lets you use peddle power with or without engine running. The two stroker could be converted to run on alcohol too ... YouTube - Bicycle Engine Kit - Install &amp; Test Ride.

Yup, too bad, the vids are good. Here's the link---> http://bikemotorparts.com/page05.html They don't sell engines but they do have links to scooter engines (chainsaw engines ... ?) and even free plans for the kit if you're a good machinist. I do think 150 and 200 mpg estimates are exaggeration but you should get 70 to 90 mpg. The kool part is no drivers lic, tags or insurance for a 30 mph commuter.

Re: Motorized Bicycle Kit From what I've heard about using ethanol in two strokes, you need to use a higher mix ratio of oil than you do with gas. A main jet a little bit larger also.

Re: Motorized Bicycle Kit I ride a 1203 cc BUELL, gets 48 mpg around town, and 56 on a seriously HIGH speed road rally. More SANE touring mileage is 59 to 60 miles per gallon, keeping to steady speeds under 75 or so. The point is, you dont have to ride a mouse engined bicycle to get reasonable economy, but if that is what you are looking for , enjoy the ride.

Re: Motorized Bicycle Kit Great thread BSD.....this is the motor I'm looking to buy.... Mitsubishi TLE43have to buy the tank seperate but who cares. I'm a 2 stroke guy have been for years. I'm with you 100% on any motorized vehicle that doesn't have to be licensed and bikes are a blast around Santa Cruz.

bsdetector | 05-27-2008 10:53 PM
Re: Motorized Bicycle Kit The TLE43 is a great motor it smokes (pun intended) all the little Honda four strokers for power ! That little ETON motor I posted is only 41.5 cc but puts out 35% more power than the Honda 49cc scooter motor. I think you'll need a minimum of 2 hp to do the job. Just look for a full crank two stroker, those half crank weed eater motors won't last. I'd luv to motorize one of these ... http://home.comcast.net/~shamansdrea..._Hagg_Lake.JPG

Re: Motorized Bicycle Kit Yeah the Mitsubishi puts out some power but the eton motor is bad ass ! waaaay better build quality, I had forgotten all about them....the hondas Mitsubishi and the like are decent for their intent....compared to that eton they are throw aways. Did yours come complete? I found them at SCOOTR.com where you buy the basic motor less clutch ,carb,coil, motor housing , pipe and recoil start....once you order the necessity's plus tuned pipe your over $500.00 less shipping , using the stock pipe would save $100.00. Is your source any better for price ? does it come complete?....the more I think about it the more I'm inclined to go with a stock pipe, depends on annoyance factor, but if stock is a pig then I'm back to tuned.

Re: Motorized Bicycle Kit A question about ethanol (C2H5OH) for engines: Can you use home destilled ethanol for an engine that can run on C2H5OH. The maximum conentration you can get is 96% and the rest (4%) is water in a home destill unit. If that is not possible, does anyone know how to get rid of the remaining water in the destillate? Good points, BS, about licence, registration and OWNING your vehicle, but I guess the homeland security could decide to seize these types of transportations too...

bsdetector | 05-28-2008 05:59 AM
Re: Motorized Bicycle Kit @ Nub - I got the Eton engine (everything except gas tank) off ebay for about $100, check their listings. @ N/A - any two stroke engine will run off methanol or ethanol at 95% concentration, just drill out the carb's jets twice diameter and mix with higher oil ratio. Don't be surprised if the carbs frost over while running.

You a tinner ? Kewl With your cousin's metal shop and your background you should be manufactoring you own kits for sale. (hint, hint ...) Check out the plans page and copy the mechanical parts drawings. The design is not patented.

Re: Motorized Bicycle Kit 01-19-2007, 12:16 AM Blaze Senior Member Join Date: Jan 2007 Location: Orange County, CA Posts: 158 I got a ticket from a motorcycle cop in Orange County, CA. No helmet (that was my own fault 'cuz it's actually required here), no registration, and no insurance (I actually had a motorcycle license on me, so no ticket there). I went to traffic court to plead not guilty, but when I told the judge it was a bicycle with a 2-stroke motor on it, and not a motorcycle, he just dismissed the whole thing. As he looked at the ticket, I politely told him that the make of the bike, "Nirve", is a bicycle company, and the VIN number was really just a number the officer wrote down from a sticker on the bike. That pretty much ended it. Not bad I guess, considering I drove it all over that neighborhood for over a year and only got stopped once. __________________ -Blaze Nirve Switchblade Chopper with 50cc chinese 2-stroke & centrifugal clutch

Re: Motorized Bicycle Kit In Washington it is a moped, and license, registration, etc. are required. Electric on the other hand is a bicycle up to 1000 watts and limited to 20mph.

Re: Motorized Bicycle Kit In that case I would push the limits for a legal electric. A lot of good technology out there. Consider this, Lance Armstrong can average only about 100 watts of power over a typical race. A good designed e-bike would have the power of at least ten Armstrongs pushing it. My little gas engine only produces about 1600 watts of power.

Here is a thought. Why not have an e-bike powered with a methanol fuel cell and the methanol is filled up in the hollow frame of the bike...

Re: Motorized Bicycle Kit I just researched the matter a bit more. You can even have ethanol fuel cells. Ethanol provides 8 kWh of energy/kg ethanol http://en.wikipedia.org/wiki/Direct-ethanol_fuel_cell . If we assume an efficiency of 40% in the ethanol fuel cell/electric engine system , you would get 3.2 kWh of work from only 1 kg of ethanol. Which would answer to 32 hours of Lance armstrong biking! I would assume that this gets you about 1000 miles /gallon without using any muscular power at all!

Neuro Artist | 05-30-2008 09:51 AM
Re: Motorized Bicycle Kit I was a bit off regarding the calculations.. Lance armstrong actually average around 32 mph. So 32 hours /1kg of ethanol would get you 1000 miles. And I guess a gallon would be the equivalent of 3 kilos of ethanol. So in all 3000 miles to a gallon! Wouldn't that get you across the states?

Re: Motorized Bicycle Kit The 50cc gas scooters are selling like hotcakes around these parts. I prefer the converted "hybrid power" bike .... fewer parts, cheap common repair parts, cheaper tires, cheap engines readily available, no expensive OEM parts, etc ... And you travel incognito, very low profile with peddle back up power. BTW, the 41.5cc Eton motor fit perfectly !

Could you convert that into calories that Lance would have to consume to achieve that? Just wondering about the efficiency of the human body.

Re: Motorized Bicycle Kit If Lance is pushing 32 miles per hour on an upright bicycle, he is using a great deal MORE than 100 watts doing it.

I would imagine he is using more than 100 watts average on a bicycle race too. I read that he could generate the equivalent of 500 Watts to the pedals over a 25 minute period on steep mountain hills. So if he were only to generate 100 Watts average that would mean that he would average for instance only 50 watts for the next 4 hours. His average is probably well over 200 watts IMO.

Re: Motorized Bicycle Kit HEY!! where has BS been ,do I have to start a WTC conspiracy thread to get him to show up :tongue_ma: I finished the motorized bike last night did a little tweaking this morning and fired her up.... tons a fun and lots of looks and inquiries from the towns folk (very small town). I hooked the throttle up to the rear brake cable so no rear brakes until I buy a throttle lever tomorrow or the next day. Great motor BTW starts on the first effortless pull every time. I went back to motorbikeparts.com and noticed the kit is now $189.00 up $30.00 from when myself and BS purchased....and they won't be available for another month or so. I hope BS shows up he's supplied all the info for this project , my first foray into the motorized bicycle arena (prolly EV next). I owe him much thanks...the few Pms we shared back and forth proved BS to be very personable, hell I'll go a step further....even likable ,he's a good dude and an asset to GIM. Some people talk the talk but he strikes me as the kind of guy that walks the walk....probably a good loyal friend to someone. His battles/debates with Rodin and others are epic and made for some long informative threads.... Just thought I'd paint " bsdetector " in a different light.:applause_

Re: Motorized Bicycle Kit I got one of these engine kits, when gas first went to $3/gal but mostly to play with. 200 MPG is not unrealistic, at least with the 35cc 4-strokes. Golden Eagle and Staton are two of the better kit names, and use name-brand engines (Tanaka, Robin, Honda) that are almost maintenance-free. The generic Chinese 2-stroke kits are inexpensive (half the price or less, of the above) but tend to have lots of issues--many of which are preventable, but you are still limited by the fact that the engine itself is rather crude. The bicycle may have issues that spring up as well. Some kits fit on lots of different bikes, but some bikes will work better than others. The main drawback of most of these kits is that since there's no engine gears, they cannot climb hills well. Only the recent Staton/NuVinci kit allows variable engine gearing. Early reports say that it works very well, but then, it costs $800+, which is about $200 more than any of these other kits cost. The NuVinci hub costs ~$400 alone, but it is the ONLY bicycle multi-gear hub available, that the manufacturer says is strong enough for motorized use. If you want a vehicle that you can still pedal far without fuel, then these can be useful. Otherwise, they're basically toys--and buying a cheap imported moped is probably easier and less expensive overall. http://www.motoredbikes.com/ is probably the best English-language forum for gas-engine motorized bikes right now. -end-

Bill, I don't have anywhere near $800.00 into this kit.....the kit $150.00, the motor $93.00 shipped, the bike ,cruiser style $50.00 (it was a return) $35.00 for a 1 gal. tank and $22.00 for various parts & pieces.... for a grand total of $300.00 and it goes up much steeper hills than I thought it would .Your right though it's a toy, but that ain't a bad thing :D
