I read the new issue of A to B this week. They did an in depth review of a bike available in Britain called the Nano Brompton. It's a regular 3 speed folding Brompton L3 bike fitted with a new motor - the Nano.
These guys have been reviewing electric bikes and folding bikes for years now and are generally pretty skeptical. The total weight (including battery) is 18.8 kg (41.3 pounds). The motor+battery is about 11.6 lbs. They suggested other Brompton models (the 52LX) that would bring the weight down to 12.8 kg (28.1 lbs)
The lithium polymer battery was rated for 266 Wh.
The amazing thing is that they rode this bike, with pedalling and motor assist, for 47.9 miles at an average speed of 13.4 mph. And, just as I'd want, the motor responds to slowing speed on hill climbs by contributing more power with it's peak power tuned to around 10 mph. The bike climbed reasonable hills at over 13 mph and could do steep ones (16%) at 7-8 mph.
This sounds like a pretty big breakthrough in range. A to B was very surprised by this result. It's more than twice what their favorite electric bike of all time (the Giant Lafree/Lite) can do. And the bike, with motor and battery, is still light enough to ride without assist.
Anyone have any experience with this Nano motor?
