How can you be sure about that?The only important point is that they won. I'm sure the Bosch guys had whatever they needed to adjust their motors too.

If you worked for Bosch and your motor was going into an important race and you had access to the Bosch programming equipment, what would you do? Would you wait until the Cheapo Chinese motor had won the race, or would you try and give your guys a chance of winning?How can you be sure about that?
Nominative 250 W motor. Everyone gets the same battery. The winner goes the most distance. Next race everyone changes bikes, if the same rider can win on several different bikes then we need to factor in rider performance. Riders cannot be card holding members of road racing clubs? Special prise for fastest bike. Special prize for team with the oldest riders (riders have never held a club card). Lightest bike award.The race needs to be done with the same driver,and it needs to be done with the bike as it is sold in the store to give the right picture, a hot rodded competition with diffrent drivers doesnt tell the normal buyer that want an legal bike much.If you want potential than just buy a bbs02 250w and change the battery and controller to 48volt 25a.
Why not just try the bikes yourselfNominative 250 W motor. Everyone gets the same battery. The winner goes the most distance.

A closer analogy might be buying a Bosch is like buying Apple iPhone or iPad. Within the walled garden they inhabit, they cannot be bettered, and they do their best to stop you getting outside. Premium product at premium price. Just like in the old days no-one got fired for buying IBM, the same is true for Apple...As d8veh also says in his earlier post here, it's the versatility of the MaxDrive that appeals most to me: It would grate with me to not only pay a premium to buy a Bosch (or Yamaha) drive, but to then be locked in to buying overpriced batteries/chargers, extended wait times for repair, and paying extra to tinker by using third-party dongles - to derestrict, tailor settings... and even then, having paid through the nose, your display is (most often) still showing wrong information.
Buying a Bosch CD seems to me to be akin to buying a speed and power-restricted BMW with the bonnet welded shut - you can't even change the oil or top-up coolant without permission far less attempt any minor adjustment or repair. With Bafang, not only do they enable you to freely tinker with virtually anything, the tools to do so are readily available (i.e. the cable and software to program the thing)l
I've had hub-drive bikes hauling my 115kg lard-arse a few miles along a level road and physically smoking... the 36v MaxDrive on my Greenway hauls may fat arse up some seriously steep inclines with power to spare... and I haven't even "pimped" mine as several other owners on this forum seem to have done. Any reports of MaxDrive failure here? No. Not one.
It's annoying that several Chinese makers offer these excellent motors on MTBs, Hybrids, Tourers etc at far less than any equivalent Bosch or Yammy drive (Apollo bikes as one example), yet very few importers here in the UK are picking up on that.
I hope you, Woosh, pick up that mantle and expand your soon-to-be released MaxDrive with other frame/style variants.
.. that's a bit disparaging as a putdown of 150 years of electrical machine design. The bearings and gears is where the mechanical failures take place.A motor is some copper wound around a core, a bunch of magnets, a few bearings and gears in a metal box. The controller is where things get interesting...
I think that the max has more potential. I am not surprised it won that race and we certainly need more races to advance the technology.
Yes, that saying originated in the 1960s and 70s when IBM dominated firstly the mainframe market for business-critical applications, and latterly the embrio PC market. But even IBM eventually woke up to realise that other far more dynamic businesses were doing those things better than they did, and IBM sold off and withdrew from those markets.Just like in the old days no-one got fired for buying IBM...
In this context it's Bosch who are the upstart, Suzhou Bafang are a long way into their second decade in this market, while Bosch joined much more recently.That Bosch stage an e-bike race at the Nurburgring which they fully expect to win hands-down, and then get slaughtered by some upstart Chinese Company called Bafang,
Yes, quite so. But we're talking about Brand perceptions in the Western World. Throughout Europe, people know and are comfortable with Bosch or Yamaha's crank drive... whereas Bafang's MaxDrive is/was to many ordinary folk something of a lesser known and unproven entity.In this context it's Bosch who are the upstart, Suzhou Bafang are a long way into their second decade in this market, while Bosch joined much more recently.
And I doubt Bosch matched Bafang's 1.2 million motors and systems in the last full year figures, larger than the entire European market.

the standard design for a full-sus MaxDrive, available from more or less any e-bike factory in China is as follows:However until someone who knows how to design a decent quality nice to ride mountain bike uses it in their designs it will remain a niche product.
Exactly, it'd be junk in one ride. Fine for pottering around town, but that's no mountain bike.the standard design for a full-sus MaxDrive, available from more or less any e-bike factory in China is as follows:
