Brompton nano electric bike

My pride and joy! This is the product of 5 years work to build the 'best' electric folding bike. This is a real humdinger!! The motor kit adds just 12 pounds to a bike (5 pounds for the motor, 7 for the battery and controller). It does 15 mph and tows my 190 pound carcass up 14% slopes.

Great to get constructive fb! My son was the cameraman in the car park, but I had to do the rest alone. I have bought various bike and helmet mounts, but this w/e we are going to set up some video location for my latest 28mph Brompton! I hope to crack the 30mph barrier.

Pity I can't have use as Director. I made sure my foot was in shot for my Pashley tricycle videos, to show the hill-climbing without assistance.

Stay tuned!

Why did u put the motor on the front wheel!? On a brompy the frontwheel has very little traction, the bike is extremly front light.

[mrmotorvator]

Good point, but there aren't many options, with a rear hub gear. I have tried a single speed brompton with a rear hub, but because the rear fork narrows there is extensive work. I have encountered some front wheel break-away, but only on very steep hills (1:6). By then you are standing on the pedals, but can retain traction by leaning on the bars. Although the battery is quite light (2.6kg) having it in the front luggage helps!

all the best, Tony

nice vid! You went off-roading too =)

Also the bike looked pretty stable for being small.

[mrmotorvator]

Although we say the motor is for road/town use, I have ridden mine off pavements, over cobbles and across fields for the past year!

I don't like gravel, though, the wheel is all over the place. I skipped that section at the Presteigne rally in 2007!

all the best, Tony

Epic camerawork between 0:52 and 1:30... not.

Unbelievable. Couldn't you have found anywhere better than a car park full of cars? So that you could actually see the subject you were filming, throughout? And try to get the camera on the whole cyclist, including his legs, not everything but...

What is a "nano"

[t83rg]

I'm thinking of buying brompton.. it seems the ultimate bike while travelling longer distances with train or bus or boat or plane.

Installing electric motor is a good extra, maybe I'll need that some day.
