But their performance oriented off road only offerings use chains. Such as the Bukk.
His point of view isn't the rebuttal; you posting a third person's point of view as a response to my personal experience was a rebuttal. He didn't respond to my experience.Just because an alternate point of view is presented does not make it a rebuttal.
You did. And you want to argue about it without any personal experience. I really don't get it.I have Zero Experience with bike belts

I rode motorcycle all my life, and I gave them up when electric bikes came out.my last experience with a motorcycle was that it was boring to ride and that invovlng pedaling along with the assist is just right.
That is why I retrofitted a Kindernay VII to my Boxxbike, and implemented Torque sensing pedal assist on itthat SEM Darhu for example is way nice but seeing that derailleur based drive on there gives me the heeby jeebies but you have to give it to the Italians for takingsomething with a motor to the next level artistically. And yes I would even spec a belt. The gearbox could also be either manual or automatic to meet the MoPed regs..
So many options but it is the unobtanium things that keep me up at night. Like a 4000w internal geared mid motor.That is why I retrofitted a Kindernay VII to my Boxxbike, and implemented Torque sensing pedal assist on it
But I agree a mid drive motor with integrated gears would be the way to go.
Valeo / Effigear new geared motor is the first step in that direction for lower power bikes
BMW has also had belt drive bikes for some time.Nobody's been doing belt drive bikes (motorcycles) longer than Harley-Davidson. An MC I own and purchased new in 1990 has a Gates final belt drive. They look just like an bicycle drive belt, the pulleys have flanges though. HD has used the belts since the 80's and they are tough and long lasting, 50 to 100k miles. They do rob power more than a chain, an unimportant fact on a motorcycle. Mostly maintenance free and very clean.
Belt drives aren't well suited for off road riding. Dirt degrades the belt and pulleys, and small stones and pebbles can get lodged in between the belt and pulley, severely damaging both with the possibility of catastrophic damage. A little stone could literally stop you on a dime. I'm a believer, but I wouldn't want one for off road.
Reading through some past articles about belts and off road, I just read this on Cycle World. The short article is about Harley choosing a chain for their Pan America adventure touring bike.BMW has also had belt drive bikes for some time.
It's an interesting callout RE: the belt drive, and as someone that's gone across a country or two before, I don't disagree with the claim on belt drives not being ideal, but - on bicycles, I suppose it's relative. Motorcycle chains by comparison, are quite beefy and strong. I'd wager a typical gates belt that can fit on a bicycle isn't all that far off on strength vs other applications and 'might' be significantly more durable than typical bicycle chains.
Everything else said is true - more moving parts = more places for random stuff to get jammed into.
Absolutely on all the reasons. #3 is critical if you're doing something 'remote' like Alaska to South/Central America - good luck on a replacement belt. Worst case on a chain is everyone packs some spare masters and a breaker or hacksaw/multitool, or even some strong wire for 'total limp mode' - not possible with belts.Reading through some past articles about belts and off road, I just read this on Cycle World.

Comparing final drives on The Motor Company’s There are good reasons to adopt belt drive: It requires no lubrication, lacks the sound of a roller chain, and cannot stretch because it doesn’t have a chain’s 100 or more joints to wear. So why back to chain on this new “adventure-touring” model?
Ready for whatever you can throw at it? Harley-Davidson has equipped the new Pan America with steel roller-chain final drive, not the usual rubber tooth belt found on the other motorcycles in its current model line.Harley-Davidson
I phoned Paul James, Harley-Davidson’s marketing channels manager, and asked him. When he called me back on the same day, he said the official answer is threefold:
- Pan America is an off-road application. The subtext is that in that environment, Foreign Object Damage (FOD) to a belt is always a possibility. A pebble getting between belt and sprocket can break belt fibers.
- A steel chain affords more durability in the worst conditions—think mud, sand, fording streams, etc.
- Repairing or replacing a chain is comparatively easy anywhere in the world. Chain is “made by the mile and sold by the foot” while a belt can’t be repaired and a replacement must be exact.
Honestly, If an ebike that I really wanted, just had to have, had either chain or belt it wouldn't stop me getting the bike. I just wouldn't go out of my way, or pay for belt drive. I'd also be a little ticked off if stones forced me to replace a pulley or belt. Chains are cheap and easy to find, available even at Walmart in a pinch.
