As far as I can tell the intelligent sensor fusion is controller software reading those three inputs cadence+speed+incline and adjusting power delivery accordingly, hence low cadence+ low speed+ steep incline = more power. I’d be interested to read riders impressions about it’s sensitivity...

Thanks Stefan, that link shows some bikes using the system. Re: no torque PAS sensor, I typed that because Honza Galla reported it, and the Bosch Technical Data section on the link you posted says it uses a cadence sensor in the small print para 11. There is an FAQ stating “Intelligent sensors...

The Bosch Hub Line with a PowerMore 250 battery has similar specs to the Aikema rear hub motor and small battery on my Urtopia Fold and I wonder if this might entice folding bike brands? An OEM Bosch hub solution might appeal to Brompton & Bike Friday, and in the UK the ARCC conversion kit for...

When can we expect e-bikes with the new Bosch rear hub motor to appear? Seems like a good move for them to integrate it with their Smart System including the LED Controller or Intuvia 200 display and the Ebike Flow app. Journalist Honza Galla described the specs including 45nm torque...

That would be great for US owners, but UK & EU rider may be out of luck.

500 mile update. What I like about the Urtopia Carbon Fold 1: - The Aikema motor is great. Quiet, strong enough (42nm) to haul me up hill, and capable of propelling the bike at 20mph on flat land. - The torque sensor is well set up, delivering power within the first quarter turn of the cranks...

See In the US you can buy a replacement battery. EU and UK customers however are out of luck because they do not ship to the UK and they closed their EU operations at the end of 2025. A 3rd party Yosepower sell a compatible battery in the US but It’s unclear if they will ship one to their UK...

Yes, it seems an electric bakfiets with the Shimano EP6 motor is selling for six grand from Amsterdam Bicycle Company. Comparable models include the Urban Arrow Family, now seven grand with the tariffs which is a tough sell when the Trek Fetch+ 4 with a Bosch Smart Performance motor is five...

Glad they resumed sales, sorry about the self-inflicted price increase that makes Cargo e-bikes more expensive for American parents, it’s not like this helps US competing brands like Bunch Bikes which also have to pay the tarrifs on their imported-from-China cargo trikes, this administration...

For several years I commuted on a 36v BBS01 diy ebike conversion. Two years ago I bought a 48v Bafang hub motor powered RadExpand, it was able to climb hills on throttle alone but the bike was too heavy for me. I traded it in for a 36v Class 1 Urtopia Fold weighing half as much, with a battery...

Brompton CEO on how tariff uncertainty obliged the brand to close its Brompton Junction stores in the US https://bmmagazine.co.uk/in-business/brompton-bikes-us-tariffs-china-expansion/

Hi Kevin, A friend, Greg Maasen, has ridden across the US on a Riese & Muller with dual batteries, a Bosch CX motor, towing a trailer and heavy camera gear for his documentary, about 416lb/188kg weight of bike, rider, & gear. He averaged about 100km/day and also recommends reinforced rims and a...

UL and Amazon sue three Chinese Ebike manufacturers over false claims of UL certification, source: BRAIN

The new C-line electric is in stock with REI

Since I posted the original link to the BRAIN article in March 2024, the functions of the CPSC have been partially transformed from the intent of Congress for it to be an independent product safety focused oversight body. It has been reported the current administration first fired three Democrat...
