Hacking

[Mark S]

I was a keen cyclist until 14 years ago when due to an accident I was told separately by 2 knee specialists that I should give up cycling. The reason they said was that I must not cycle up hills. With the advent of E bikes it seems likely that I can cycle again so long as I can use E power to get up the hills. As some hills will be very steep and I weigh 80kg, I figure I will sometimes need significantly more than the 250 watt continuous power available with today's restricted motors. As I understand it Australian regulation are pretty much the same as in the EU, and so there are regulatory issues I would need to address if I went down this path. The Flyon motor, with its 3 power levels, will not be in any bikes until around mid 2019. Can anyone please advise what continuous watts the Brose and Braun CX motors can provide when derestricted?

A derestricted bike will not produce more power than the designers intended it will just continue to give assistance up to the limit of your gearing (depending on where the restriction is raised to)
For hill climbing i would think you want to pick a motor that responds best to cadence

 

[Mark S]

I do get your point, but .... what is going on with TQ and the advertised data for their Flyon motor:
TQ HPR 120S Rated Power (W)250, 500, 920. Torque (Nm)120, 120, 120?

 

[ccrdave]

I think thats a bit more than just removing the restriction it would mean a rewrite of the firmware to acsess the higher power above 250 its not a pedelec anymore

I have used blevo and Zworks with my Levo the zworks is best on the IOS platform and blevo best on the android platform, they both do the same thing the Zworks author is the original "inventor" of the system I personally use the zworks sport ,power and madness settings depending on what im doing and I think its a massive improvement on motor response, and response is the keyword here the motor does not produce more power than the manufacturer intended, its just the way its provided.
I have had discussion with the author and in particular I asked why when the motor current is set to zero you get a much more responsive motor. His answer, "the specialized software has a bug" you can make of that what you will!!
the apps also allows to remove the speed restriction, thats a personal thing but just to reiterate you do not have to use that function to realise the other benefits and its illegal to use an unrestricted bike on public land

 

[Sjc501]

Do these apps work with an already unrestricted levo?

Yes but depends on what version you have

Yes but depends on what version you have

Yes but depends on what version you have

version of what ?

HOW TO INCREASE EBIKE SPEED LIMIT USING THE LCD DISPLAY. Increase speed from 19 mph to 28mph, this works on Juicedbikes and Pesu ebikes maybe other e bike brands. .......... This is the Wiseview CS280 Display ...

Hi all

Checking in here to see if anyone has had success with the 2019 Levo. I'd like to get past this 20 mph cut off if there is a way.

Thanks!

I would've thought for hill climbing you'd want to pick a motor that responds best to torque?

On my Merida e160 900e (Simano Steps E8000), when my cadence drops off so does the assistance, it's like it wants me to use my cassette range more rather than my motor.
When I'm in the correct gear even with a slow cadence just a firm push on the pedals brings the motor back into play, makes it great for lofting the front wheel up steps and rocky jump ups.

Who would spend that kind of money on a new bike and throw the warranty out the window as the first thing they do!
Seems totally mad to me.

On my bike the presence-history of a speed delimiter is not detectable nor provable.
But if the seller had left me the choice: Warranty or speed delimiter, I would have chosen the second.

"Hacking" is a bad name, for what, if done right, works amazing. Purchased a 2019 Kenevo. Within 1-2 rides thought I'd made a mistake, as the motor restriction was way to slow for my average speeds. After checking on hacking methods, settled on "Lite Blue" which simply "told" the motor the bike had 20 inch wheels. This was a game changer. Unlike most EMTB riders that want some fast shuttle up, to simply go downhill, I also use my bike to go fast through the single tracks, in the woods, up and down, all mountain. Have spoken with others who have had trouble with the longevity of the motor, as it comes from Specialized. I actually love to ride uphill in ECO mode, and cycle in and out of higher modes, constantly. As a consequence, my motor is phenomenal, virtually silent (have heard complaints of noise) and works better, across ALL modes, extending my battery life for rides beyond 25 miles. When I buy another Ebike, I will "hack" it immediately. It is ridiculous that, if a motor is used for various wheel sizes, that changing these settings voids the warranty?!?1 Especially when my bike has run better, and keeps running better, all the time.

This has absolutely nothing to do with your "hack" and everything to do with Brose's abysmally variable build quality.

 

[SurreySteve]

So where is this now ? I've got a Gen2 Bosch and derestricting the speeds is not particularly high on the list of stuff to hack.
I'm more worried shorter term with updating firmware without involving a dealer if I want and enabling walk mode and playing about with power bands. At some point I'll need to build a new battery and I don't even know if that will brick the bike without some security removing.

I agree. About 1 out of 4 of these Brose are very good. Got lucky on mine. But it does further prove the point that derestricting does not adversely effect the motor. They are made to produce the same power regardless. What is really driving us crazy is that my son just got a Creo SL Sworks. The SL motor on his bike is tuned wayyyy faster and better than the Kenevo SL we tested. The whole 15-18mph cut out is ridiculous, when this Creo goes past 28mph before cut out.

It's a bit of a myth that de restricted means faster . A good rider can pump out enough power over the cut-off limit to do the same speed as a de restricted bike . Shore you can hold speed longer and easier . But faster . Hmm kinda But not really .

In varied terrain, featuring jumps, not simply downhill, first rides on my restricted bike put me in dangerous situations. How? Try riding at the limit as you approach a jump. If a 53 pound bike “cuts out” approaching the jump you can be in a world of hurt. Have been riding motorcycles 50 years and MTB since late 70’s. Derestricting my EMTB was mandatory to get the most of a big bike’s potential.

Perhaps you have not ridden the type of terrain mentioned, or do not have experience riding or racing against analog or restricted ebikes. There is no way, at least how my bike is ridden, for these riders to keep up.

 

[Dago]

@ 120rpm i can nearly hit 40mph on the flat and not 1 race bike rider can keep up or even keep me in sight.

If it was about pure speed and no turns….from ex pro motocross and enduro rider. There is always someone faster, isn’t there?

Are you still running the 21 tooth front chain ring and the 10 toothed SRAM Eagle 12 speed cassette?
If you are, I'm sure that set-up doesn't equal 40mph @ 120rpm.
