Are they abandoning the Levo SL or is this just a stopgap?

Embt is a niche in the large ebike space, and I agree that regen may be better suited for other applications. All the way from adventure/SUV type bikes to cargo.

Full suspension "adventure" type bike with spring tensioner pushing belt up just below the chainring. Same design as Pinion MGU. Initially I had the Bosch dynamic setting set to +5 in turbo (power agressively coming on), and I think the belt cog jump may have been from standstill. I've since...

2 different teams of engineers (probably in different companies) that can't do each others job, so this will happen in parallel if we like it or not :) I see regen as a net positive. We get some additional charging. Speed is controlled on decents (grandma could set it to come on as low as 20...

Remember the Zeroshift transmission 20 years ago? Was destined for road cars. Not quite the same tech as F1 uses, but both systems temporarily engages 2 gears meaning uninterrupted power. While the transmission worked, it created a big ask of the engine and driveshaft to match the new rpm. At...

Worst case the belt will skip a cog or come off? Assuming there is a tensioner. The last month I've had 3 cog skips, or at least that's what I think is happening. Something akin to a worn chain jumping a tooth but with a different sound.

I am currently riding a belt driven cvt in the form of a Bosch motor + Enviolo hub for commuting, touring and the odd excursion on easy trails. Being a crude version of an ecvt, it's been mostly great. The main drawback is the heavy hub which will be solved with a motor/gearbox. Changing gear...

Agree. I could see an ecvt full fat enduro bike + a SL trail bike with mech shifters being a good combo for 2027.

You could have 2 tensioners, one for each direction?

I guess we would need some new brake levers which relay the lever position to the control unit. Another component that needs to be powered :)

For sure there will be a delay in forward motion when you press that pedal hard and fast. May feel like a slipping clutch.

I asked AI how much regen force a Gobao X1P could possibly generate. 0.4G peak, apparently. There's a lot of variables and the math could be off. But if true, that's pretty good.. So paired with a hydraulic front brake, we'd probably only need a one pot 140mm rear brake. The pads would last for...

I've looked into planetary gearing a bit. It's very flexible and you can configure it in a number of ways. The sun gear is sentral here, as is the possibility to lock it with an electromagnetic brake (no current = locked) or a sprag clutch. 1) Sun gear is only allowed to go forward: When...

I was commenting on what will happen when the battery is dead or disconnected, however unlikely. You think moving the pedals will force the bike forward in this scenario?

I'm unsure if the bike will move at all when the battery is dead. The motor that is responsible for the rider getting a sensible cadence will spin freely, if I'm not mistaken.

I like the idea of a mechanical front brake and a re-gen rear brake. The rear brake would not work very well when the battery is at 100%, though.

Well Brose did show a motor/gearbox concept 2 years ago. Could be still in development, destined for the Levo 5?

I have some experience with a Tailfin rack on the Levo 4, and also with a heavy Enviolo hub + rack on an Orbea Muga. It comes as no surprise that you really don't want a lot of weight on the back wheel. The Levo 4 X will obviously perform a lot better due to this. On the other hand, as long as...

Without power you'd just spin the internals around like you're in neutral, I think.

I really hope so! The Pinion MGU was a bit of a letdown, would be grand if Avinox released a powerful eCVT.
