Yes, but with Bosch it is an identical motor, its just the fact that by removing the speed limit you automatically give it the higher nominal power output.
The power they are capable of is a different number to the nominal power.
Other brands might use different motors for their sPedelecs..... It could well be the same, but I think you might have just got a small bit of information and be running with it like its a fact.
I mean it might be that Brose have the same motor, but I suspect you're just guessing.

it would not be cost effective to make 2 motors 1 250w and 1 350w for the different bikes so its done buy software at the manufactures.
its why if you have a sclass motor you have to send it back and get a replacement from bosch as you cant change the motor settings with what you have on a 250w motor.
some say that a bosch could take as much as 700w but untill it gets the software hacked we will never know.
even the bms can bus data and is password protected thus why no batts from china as cant get past it atm.
i also bet the only difference to a 250w and a 350w is the speed limit.

Hi Wicky you do need to register any and all speed e-bikes to avoid risk of loosing your shirt post 'incident' but there's no requirement to display a number plate (in fact you won't be issued a number to display when you register it).
You might think that this is more meddling from our dear leaders ... after many years (10!) promoting e-bikes as a viable alterative to motor cars I'm just happy that UK Govs of all colours have (to date) not required us to register all forms of pedelecs. Did you see the news that China has banned e-bikes? ...imagine if big auto and oil had that much influence here. Chinese men and women bought c.39 million e-bikes last year - car makers and fossil fuel sellers the world over don't like e-bikes.

Hi Jon, BULLS EVO models use the small LCD toggle switch mounted in easy reach of your left thumb, beneath the same thumb is a small yet clear gold coloured screen giving all info needed. It's a clever design, following the less is more principal. Last year's BROSE display was center handlebar mounted but like all things located there they suffered during a tumble (2 of my 3 recent spills at Cannock Chase knocked the display off). Dispite it's micro size the BULLS display includes a USB charge point for sat nav or phone charging.
I'm sorry you've not found the info you need on BULLS and BROSE systems; be asured there are many good reasons we've taken on these manufacturers (design, engineering, performance value for money to name a few) Email or phone if you have time, if you don't I'm happy to tell all here but wary of 'promoting' products on this forum.

Hi Dave max speed is not 15.5mph, it's 17.3 (25kmh + 10% margin, which all mnfs I know take advantage of), and last year VOSA confirmed that unlike rest of EU speed pedelcs don't need number plates in the UK.
That said I agree with you, to my mind speed pedelecs really arnt worth the extra bother.

Hi Soundwave, the best way to evaluate and compare motor power is to look at their torque figures because motor efficiency varies so much between one make and another. Most makers publish this data, usually in Newton Metres (Nm). 5Nm is equivalent to the turning force at one end of a 1m broom handle while a 1lb bag of sugar is hanging from the other end ...it's a lot!
BULLS and Rotwild BROSE motors give 90Nm, Bosch varies depending on model between 40 and 60 (last time I looked), Yamaha is 75 I think, and SPARTA produce a 25Nm, a 30Nm, a 40Nm, a 50Nm and an 80Nm motor (man those Dutch are fussy!) Sparta's 40 and 50Nm models also provide regenerative braking thereby increasing range and saving your brake blocks.
For all but mountain biking I recon 40Nm is plenty.

Dunno, but recon the wires and connectors feeding an 'over clocked' motor would be the first to catch fire.
...eMTB racing is gathering support, maybe in time an un restricted class will be established - then we'do know where the limits are!
That looks like a lot of fun and love the tech but I'm a flipflops and shorts e-biker so happy at 17mph. I took a BULLS evo 3 to Cannock Chase; way way way more fun and excitement than an F40 round Silverstone, and averaged only 11mph over the day (6 hrs before back to base with near flat bat).
