I am trying to find books or a site that covers early electric bicycles. I have several electric bikes. My interest started when I had knee problems. I would like to trace there history. Roy

(not yet)for sale: I work for a export business in Shanghai looking to start exporting classic Chinese bikes to America and Europe. In the States we might call them 'vintage' but they've never gone out of use here.
Just putting a message out there to see if bike lovers would be interested in such a product. please reply with comments.

Very interested in your bicycles. What type of US regulations will your bicycles be tested to? Does the Consumer Safety Council or Department of Transportation have requirements you have to pass? nay details would be helpful.

   RE:FOR SALE:Traditional Chinese bikes posted by AviationMetalSmith on 12/13/2005 at 10:37:05 PM
The two most popular Chinese bicycle makes are the "Flying Pigeon" and the "Forever".
I hope these two are represented in your collection.

As for the question, the bikes are identical to any number of British bicycles which were built between 1890 and 1915, and there wouldn't be any "regulations".
Bicycles are subject to CPSC rules (Consumer Products Safety Commision) but not DOT regulations.
It might be best to put reflectors on these bikes before offering them for sale.

I will have a look if I can find instruction manual .
Used one of them to go to school use to run on petroleum 16cc and you could take someone with you too .Were very strong but hellish to start when they were worn .
Use to put a can with petrol under it !!!!
When it was hot enough it ran ok .
Great machines great invention .Later they were called Hispania the factory went bust and I ended up buying 1000
at 10 guilders a piece .
First hard to sell for 25 but my last one was sold for 600
I think my son has one left (gave him my last one 2 yrs ago )will make enquiries

Dear Mr. Gaede,
I am a mechanical engineer living in India. I have a special interest in small engines, and have carried out a study of the Lohmann engine. Made in Germany in 1949 to 1952, it was designed by Hermann Teegen. It is a unique design of a small two-stroke engine using compression ignition instead of spark ignition, but the fuel was carburetted and not injected as is normally the case in larger diesel engines. It worked by a mechanically complicated variable-compression arrangement.
I want to purchase a Lohmann and have been looking for one. It is rather hard to find and so far I have not been able to find one.
I want to get in touch with someone who has actually used one and would like to know his experience with it.
Since you owned one, I would like to know which fuel you have used - I understand that paraffin and not diesel is the recommended fuel. I believe people tried different fuel mixtures using combinations of petrol, diesel, paraffin, and two-stroke oil, with different results. I would appreciate if you kindly reply with a copy to my email address akhileshagarwal2000@yahoo.com

I had one of these engines in Germany,the run on kerosene
the fueltank was 1 Lieter and the fueltank cap had a small
cup attacht to it.After filling the tank the cup was filled
with 2 cycle oil and add it to the fuel.It was very importend not to have any slack in the cable whitch controled the comprecion.

anyone heard of this one.

google search=Homestead Your steam or diesel-powered bicycle.

In 1954, Schwinn mounted a Smith-type steam generator on one of their
bicycle models---it powered a mini-steam engine.

And in 1952 or 1953 I had a Willy Messerschmitt variable-compression
diesel that powered a bicycle. The compression was lowered for starting
by a cable from one of the bicycle handles. The cable rotated the
diesel cylinder-head. After the toy 3/4 horsepower diesel started, the
cable was released to restore normal compression and power.

Annoying as hell, can't even find a reference to these two little gems
in the stupid search engines.

Dear Graham,
I acquired a Lohmann in Sept 06 and have completely restored it to fine working condition. I have learnt its intricasies the hard way and made some design improvemnts. I honed the cylinder 0,2 mm oversize, made a new piston locally and fitted new rings. It is a very fine piece of engineering and runs very well on kerosene/5 % 2T oil mixture. It starts easily[except when it is worn out] and idles smoothly. It delivers plenty of power for running a bicycle at 30 kph at half throttle. I have exploded diagrams and instrution manual. If anyone needs help with his Lohmann, wants to build one, or has experience with running it on bio-diesel/vegetable oil, please contact me, I can help with advice, instruction manual, spare piston and rings.

Dear Graham,
I am writing from India and acquired a Lohmann in incomplete and worn out condition last year. I have been working on it for last six months and have restored it to good working condition. I have honed the cylinder 0,2 mm oversize and made a new piston and rings locally. I have also made some changes in the original design to improve performance. It runs best on kerosene/5 % 2T oil mixture. It starts easily, runs with low noise and vibration and idles at low rpm smoothly. It has ample power to run a bicycle with single rider at 30 kph at half throttle. I have diagrams and operating instructions. If anyone needs any help for restoring or building a Lohmann[a skilled model engineer can take it up as a project], or with spare piston and rings, or has any experience with running the Lohmann on bio-diesel or vegetable oil, please contact me.

We have this motorized by pedal AMF Roadmaster Bike, shows manufactured 5-78 with the number 030857 on the front bar, the writing before the number is worn off so don't know what it means. It has the motor on top of the rear wheel that engages by flipping a switch after you start peddling, there is a headlight, horn etc. We can not get it to even try to start my husband thinks it is the actuator? Does anyone know where to get parts, a repair shop in the Ft. Worth, Texas area or basically any help at all would be appreciated. Wanted to fix it up so my son can commute at Texas Tech University.

   RE:MOTORIZED BICYCLES:General help posted by Edward on 10/2/2005 at 5:06:34 AM
I admit to no experience w/ this type of motor, however there are the three basics to start with, of air, fuel, and spark. All three must be present and in the proper quantity. Checking for spark involves taking the plug out, reattaching the plug wire to the plug and grounding it against the engine case while the engine is cranked. This is best done without holding any of the items in hand, just laying there on the engine case will be fine, as it can be a shocking experience otherwise. Air presence can be assumed if the filter is clean, the intake gaskets are good, and the throttle engages the carbuerator.(usually moving a small piston that can be seen through the air filter opening, w/ filter removed.) Fuel presence is a little trickier to figure out, but a wet plug or exhaust port will indicate a fuel getting where its supposed to go. A consistent approach to this project may result in successful running vehicle, but it is old and these were not noted for their reliability even when new. A new Kinetic TFR might be a better choice for a reliable commuting vehicle.
