[#10460170]

For the ebike riders out there, is there a preferred motor for derestricted riding - Yamaha or Bosch?

I'm aware of their different approaches to power delivery, but when I'm on private land and want to go quicker, which one works better? have heard strong views that Bosch is preferred in this case, and would like to cross-reference with other's experiences.

6/10 reasonable trolling effort... or at least I hope.

One of those 9kw Chinese efforts.

but when I’m on private land and want to go quicker,

wonder how "yes it's derestricted but I only use it extra speed on private land" washes with plod.

If the bike is only ever used on private land then it's fine.

But as said above, the best derestricted motors are Austrian and two-stroke.

Brose (spesh) is probably the easiest (via blevo app)
All the common physical derestriction methods (chips/boxes) designed to fit motors seem to work fine. Some do have the odd quirk though. Shimano for example cuts out if you use too low a gear ratio with the type of chip that halves the speed sensor signals to the motor. (easily worked around though). and some motor designs could do with better sealing from water ingress (which can cause problems with mod chips/wiring). again perfectly DIYable.
I'd choose a motor with most of the general usage . Traits you prefer rather than worry about how it'll behave when derestricted.

it's cool having a private playground away from keyboard police isn't it? Mine's called Scotland 😉

i do find the paradox kinetics quite intriguing. ~£3k for a motor that can be fitted to pretty much any bike,battery goes in a bag which isn't ideal.

As geex up there said the Blevo app with a Brose motor is the easiest way to do it.
It also has the benefit of letting you really experiment with different motor setups.
Great bit of kit.

Private land and you only want to have a 250w motor ? wtf ?

thanks for the range of comments 🙂

yes, private land and derestricted. And also using it on standard roads in its usual guise. Am intrigued by the level of hostility from some - I do have 'normal' mountain bikes, but have an 18 mile commute each way to the train station, which is too far (for me) to do every day, there and back, unless I get some assistance. Half the trip is private land, if I goths cycle only way, and half on the road.

And when on private land for fun, then going quicker up the hills gives me more time to come down.....

If desrestricted its illegal IMO even if you switch it to restricted mode on roads. Also derestricted you might well find your battery does not last long. I went thru a 375W battery in 8 miles derestricted on the road.

Brose here on a Fantic. Just moved the sensors onto the pedals. Lost about 15% range but the cut off is gone and the bike's a joy. Ride regular mtb most of the time but special treat for solo missions.

Less hostility, more confusion that if you actually have access to private land, why not buy something that's an actual motorbike?

They even do an electric version

Interesting isn't it.. well, made I muse on why this is illegal, when cars/motorbikes that can do well over 2X any speed limit in the country are fine and dandy... ho hum.

They have type approval, VED and insurance mostly 🙂

Tinas
It might be difficult to grasp but some people would rather ride an Ebike that a motorbike.
I spent most of my youth and early adulthood racing MX and Enduro and doing pretty well at it. I even rode for the GB team a couple of times at the ISDE
I' d much rather ride my Ebike than go back to that.
Totally different buzz.
Not sure why some people keep trying to compare Ebikes to MX and Enduro bikes.

the legality is grey, and I think untested. What isn't grey is that using it derestricted on the road is illegal, unless it's licensed, insured and you wear a helmet. The fact that it can be derestricted is not - almost all off the shelf e-bikes can be derestricted, and they are all legal. So if you have a dongle, but it's turned off, it should be legal. Like having a car that can do 170mph, but only doing 70mph.

Then on the private land you can go quicker if you wish.

I don't want a motorbike - I want an ebike - not sure why it's so hard to understand for some. Motorbikes are different to ebikes are different to MTBs are different to road bikes - all have a place, surely?

I've got 2 bosch motor'd ebikes. I derestricted one as I wanted to see what it was all about. You can turn the restriction on or off with one press on the controller. Problem being even with it turned off you are still on an unrestricted bike, if you are happy with that then it does make a huge difference. On tarmac you can hold 25-30mph easily, downhill my gearing ran out at 37mph and it was easily achieveable. However to anyone that sees you it is really obvious the bike isn't restricted. It does really eat into battery life as well. On trails it is very easy to go too fast and end up in trouble, 30mph feels very quick on tight trails through the woods.

I've removed mine now as I wasn't happy being 'illegal' and didn't like how it compromised battery life. I would like the limit to be 20mph not 15mph as it makes a difference but tbh 15.5mph is enough in most places and gives decent battery life. I'd advise just buying an ebike anyway and leave as it is

tinas.

both of those MX bikes would be slower on most of the descents I ride my regular hardtail down nevermind my 170mm Emtb.
Be nice getting to the top on one though.

While i get the OP's point about a long commute over mostly private land, i can't help but think that maybe not all ebike riders will ride their unrestricted ebikes considerately.
Seems a shame that the manufacturers have made them so easy to de-restrict.

if the car or motorbike were unregistered, untaxed with no plates and no mot and therefore uninsured then yes you could muse over the comparison.

I limit mine to 24mph, I wouldn't want to go faster, faster you go the battery usage ramps up exponentially(I usually cruise about roads around 21/22 I'd guess). But, I've got a monster battery 850wh, so happy days! 😆 but still, horsing about a say 35/40 mph, would restrict range alot, I think it's wind resistance that is the biggest factor there(chime in if you know better.)

15mph would do yer dinger in, if the bike was all purpose like mine.

Gearing as well is something to consider, 36/11 on 26in wheels, 2.4 high rollers at 90rpm is only about 24mph anyhow. 110rpm is about 28/29mph.

Not really since cars arent restricted by law to only do 70mph.
A more accurate comparison would be having a switch to turn off a tachometer or to destrict a 50cc moped.
The bike is capable of being illegal at a flick of a switch. They might be a case for it if the dongle was at home instead but being "turned off" I doubt would count as a defence.

I believe the department of transports opinion was that if your ebike is fitted with any kind of toggle-able feature that allowed it to exceed 15.5mph it would be a motor vehicle - irrespective of you using it or not.

Obviously if your derestricting it you'll have the land owners permission to ride your motorbike on their land. And if that 'private land' happens to be public rights of way you can't use it there either.

I have a dongle on my bike, it can be swithced on/off with one button.
My honest advice is . . . Don’t bother.
It doesn’t improve the bike, it’s of questionable legality (at best) and it has a massive effect on battery life.
I can easily flatten mine in 8 miles off road, or 14 miles on road.
Mine is a bosch motor, it works perfectly, you wouldn’t know it wasn’t standard.
Re: legality,
It’s illegal to use it on road if it’s de restricted, if the switch is flicked to the off position I suppose nobody would ever know, but if you were involved in an accident (even completely innocently) that’s when you could have a problem, because the police aren’t stupid and they are duty bound to investigate if someone gets hurt.
I will point out that I’m not claiming it to be legal if it’s turned off, because I honestly don’t know.
I’m thinking of getting another ebike, and I’m not gonna bother with any chipping or anything, that should tell you all you need to know.
YMMV, literally.

I guess you never accelerate past 15mph on the flat then?
~ IME that's where de-restricting the mpotor improves Emtbs most rather than gaining massive top end speeds.
I reckon if the UK cut off speed were a more sensible 20mph instead of 15mph many would not bother de-restricting their emtbs at all.

WOAH. I agree with geex about something to do with ebikes.

Mark this in the calendar
