Brompton nano electric bike
Filed under electric bicyclesSep 10
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.Duration : 0:3:38

Very good – checked out the Mezzo today, after deciding against the Dahon Curve. Mezzo rather heavy (and too bulky), which only leaves the Brompton as the serious choice.Like the quick battery bag connection, too!
Brompton is definitely on my list – but is there more info on the motor/battery pack please?!
Thanks

My sister and I have Bromptons and would love to add a Nano. Once they have the Nano added, can you still use the front bag and not carry battery/not use motor? What is the cost of a Nano? Can anyone install one – does it come with instructions? What does it cost? Too cool -

totally agree. I am a taekwondo instructor and Im obviously fit as f$%k. I use an E-Bike (has pedals and similar to an electric bicycle) to commute 10 miles to work and back. The Electric is so quick anyway i only use the pedals to start so I just use the throttle at full wack most of the way. I can go on cycle paths with it and ride it indoors. Its so quick and saves me money. Bus costs 2USD each way takes 30mins the E-bike takes 40 mins cost nothing and I get fresh air and light exercise. -

Um, is this comment supposed to be serious?1) Is using a car, bus, train, or motorbike any more or less lazy?
2) The bikes only assist up to 15mph, and can’t climb hills well/at-all without leg assist, so the rider typically does 60%+ of the work.
3) Not everyone is young, fit and able bodied. Electric bikes let those who aren’t escape from cars and Public Transport, get out in the fresh air, and get some exercise.Ian

The electric bike …
The electric bike makes longer range commutes a possibility and provides assistance for people with health problems (bad knees, etc.) It also eases going up hills in uneven terrain. I got one for going to school and to the store, and I pedal while the motor provides a boost. -

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

It has a contunuous rating of 250 Watt and runs at 425 Watts peak at 42V (with a fresh battery), dropping to ~400 Watts once the battery drops to 37 Volts. -

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

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. -

We use a 260rpm motor that does 15mpg in a 349 rim. The motor can be built to run up to 400 rpm, but we mainline on 260 and 190 for bigger wheels. -

The standard battery we use is 7A/h Li-Po weighing 2.4kg, or 2A/h at 800 grammes – who mentioned Lead? -

They do start as Brompton forks (72mm), but we ‘re-set’ them to 80mm or 100mm “over lock-nut” depending on which motor we use. First we have them shot-blasted, then we open them evenly, re-braze them, then powder coat to finish. -

Are those standard Brompton forks? Aren’t most hub motors too wide for the narrow folding bike forks and small hubs? -

Great work.
Perfect for dense areas with bicycle friendly infrastructure.
Switch to lithium polymer to make it super light? -
