The new electrified Brompton has a neatly integrated front battery pack and charging port, that can be carried separately as a small bag when not in use.
Maintaining the "iconic style and craftsmanship of the Brompton folding bike", it's a similar size and weight as the non-electric version but with a 300Wh, 2.8kg battery added, allowing for a range of between 25-50 miles depending on the level of assistance used. The bike itself is fairly light, weighing 13.4kg in total.
There are three assistance levels from the 250W front hub motor, and Brompton say the bike runs very smooth manually too so you can save the power for when you need it most. There's even a torque and cadence sensor included. Brompton teamed up with Williams Advanced Engineering to develop a motor that would integrate well with a folding bike, and Brompton say the end product is their most technically advanced bike to date.
The battery/bag idea looks particularly interesting, clipping neatly onto the front and becoming a compact bag off the bike with a shoulder strap for easy portability. What's more, your ride settings can all be customised via Brompton's app, where you can also log mileage and service history.
The e-Brompton (as we've just named it) will be available with either two or six-speed gearing, with prices starting at £2,595. They won't ship out until early 2018, but you can already reserve one with a £200 deposit on Brompton's website.
If you were at Ride London this weekend you may have already got a demo - but Brompton are also offering demos at their Brompton London Junction shop throughout August, plus at numerous events around the UK. Check out brompton.com/electric for more info.
After cobbling together a few hundred quid during his student days off the back of a hard winter selling hats (long story), Jack bought his first road bike at the age of 20 and has been hooked ever since. He was Staff Writer at 220 Triathlon magazine for two years before joining road.cc in 2017, and reports on all things tech as well as editing the road.cc live blog. He is also the news editor of our electric-powered sister site eBikeTips. Jack's preferred events are time trials, sportives, triathlons and pogo sticking (the latter being another long story), and on Sunday afternoons he can often be found on an M5 service station indulging in his favourite post-race meal of 20 chicken nuggets, a sausage roll, caramel shortbread and a large strawberry milkshake.
