    Electric Powered Brompton On You Tube

    I thought that Bromptons were a bit too small and the portablity factor would prevent one from converting a Brompton into a serious electric bike. I was suprised to see one demostrated on You Tube:

    That's quite amazing. I'll have to find out more about the 'Nano Motor'.

    On the other hand the main reason I have a bike rather than a moped is that I need the exercise, but nevertheless its a very cool arrangement.

    The battery looked a bit more hefty than he was letting on... Discrete install though. Very nice.

    I had always thought that an electric assist would increase the weight by an unreasonable amount on a folder, but I recently came across a new planetary geared (11:1) hub motor designed to run on only 24V this hub motor looked to be less than half the diameter of my clyte and a 24V lithium-poly battery would be about as light as one could hope for. I was going to give it a try, but the vendor said there was something like a two or three month backorder on the system.

    VERY discreet battery install - nice! For the price of the hub though, I can almost get a C3.

    C3 is like your Merc EvilV but more stripped. It is the entry level Brommie.

    The nano motor looks like one of the crystal light designs. Like all motors on small wheels, the top speed is limited but it should climb hills great.

    "What's a C3?...Ah - of course. Stupid of me. LOL. Thanks." -EvilV

    One of the photos from my bike collection feauturing my own interpetation of a California Beach Cruiser bike using a C3 (or Companion) model from Brompton:

    http://www.flickr.com/photos/world-o...7594325178229/

    The Brompton is in the forground with one of the California Cruiser bikes (orignial 1971 Schwinn Manta-Ray bike-a big teen's Sting-Ray actually) that I used as a template in the backround. The Brompton has a Nirve (a California company suppling the beach crowd with the proper bike parts) Lounge Lizard pattern sprung saddle and a English made traditional metal three speed handlebar mounted shifter which I save for years just for the right bike to come along. The C3's bright color really adds to the beach cruiser effect without extra cost.

    The whole purpose of my biking is for exercise. I don't want to put a motor on my Brompton or any bicycle for that matter.

    Yeah, that's just what the cagers that try to run me off the road think as well. As a transportational cyclist I just have to take issue with your blanket statement.

    Blanket statement that applies to me, Landluger. I don't care if anyone else wants a motor on their bike, I don't want one on mine. I use it for transportation to get the exercise that I need. Biking gets me from point A to point B and gives me exercise at the same time. Biking for the purpose of transportation allows me the ability to incorporate exercise into my life by doing so. So you don't have to take issue with my blanket statement.

    Don't read too much emotion into my response. However, I have personally seen several non-cyclists get into cycling after many years out of the saddle via the use of an assist; and I hate to read posts on the forum denigrating these riders. Anything to bring more people into the tent, right?

    BTW, you can get as much or more exercise with an ebike.

    A study in Australia backed up that eBikes do give you a great workout, often better than biking alone. People are more often likely to plant their but on the seat just to try it if they know they can have help when they are tired.

    Was this study in Australia done by ebike salesmen?

    I love riding my bike and working quite hard on it, but I'm 56 next month and there are quite often occasions when I'm ten miles from home and gritting my teeth into a thirty mile an hour headwind when an electric motor would be a real Godsend....

    Come to think of it, there were cycling tours when I was 26 that I wouldn't have said no to a bit of a push.

    Last year I was doing the British Coast to Coast route on a mountain bike. For me, it was a three day trip and it crosses the mountainous Lake District and the Pennine Hills, where for some perverse reason, the route climbs from dale to dale, making a total of 7500 feet of climbing in the 120 miles or so from the Irish Sea to the North Sea. During one particularly steep stretch of this route, I saw a guy on a hundred horsepower motorcycle, dismount to adjust his clothing and then speed off up the hill at a huge pace. I remember thinking what I wouldn't give for just one of his horsepower - I even got to thinking that half a horsepower would make me a very happy man.




    Not my picture, but you'll get the idea. This is Black Hill, about 2000 feet asl.

    Wow, you are an *******. Thanks for coming into this thread to post that little piece of wisdom.

    Regarding that bike, it seems like it would be good for older people, or business people that can't afford to get too sweaty on the way to work in cities.

    I am neither of those things, but I still want one just to put around on.

    I can't state my opinion on something without being called an ******* by you. I think that makes you the *******. I didn't say anything offensive. I just feel the motor defeats my purpose of riding a bike. I don't care if you want a motor on yours or anyone else's for that matter.

    I can tell you that I wouldn't mind having a motor on my folder at time. If I ride to work I have about a 4-5 mile long climb that seems to never end. I have to deal with buses passing me spewing their soot right as my lungs are working their hardest. A motor would be very useful on this part of my ride.

    It takes me about 50 minutes to bike the 12 miles to work and and 1:15 on the way back. These times reflect total time including stops for traffic lights. I am normally at about 14-15mph on the flats. I don't try and push too hard because I have to wear more business oriented clothing so I can't arrive at work all drenched in sweat. There is no place to ride in more comfortable clothing, shower and then change.

    A motor assist would be a great addition at times. Especially on the days I get out late and really need to hurry home. I could use the motor and drop my return time substantially. I'll still get more than enough exerecise.

    Did anyone notice how the YouTube demonstration had the cyclist lane splitting between two cars in the middle of both lanes! I would not have done that because should he go down, his chances of getting run over by cars on either side are great.
