May 6, 201411 yr As some have also posted I find the eco setting a waste of time and the jump to tour is too much for me as it means I have to pedal at 16 or more mph to stop using the battery.. In eco its just too hard on anything but a flat road (with no head wind) Until recently I was a semi pro photographer and was able to afford some half decent kit, but as in most things some bright spark came up with an easy to apply hack for the camera firmware that unlocked some extra functionality of the cameras! Now unless I am totally wrong, the bosch system is run by some sort of processor which must work from its firmware instructions and may be hackable perhaps? I know about the dongles that fool the system to make it go faster, as were available for cars until someone found out how to rewrite the engine maps with a laptop. So, there must be some clever dick out there with the know how to do this....... Answers on the back of a cigaret packet please!

May 6, 201411 yr Appears to be written in a language I don't understand. I was going to say Chinese, but it's a word that is perhaps a bit over used on here. It is Dutch and Dutch/Flemish is my mother tongue and I know the blog but never read somehing about hacking the software there. I too have thought that it must be possible to 'hack' and rewrite/alter the firmware. Problem is the interface/diagnostics box you need to hook up your laptop to the Intuvia/motor. I think dev8veh can do this but won't tell us
May 6, 201411 yr Haha! No clever dick can hack this one.. I have full access to Bosch diagnostics kit.. You don't think I have had a play!?... If you do access the internal software, then don't bugger about. Just in case you do mess things up, Bosch can see and all warranty void! Regards Martin
May 6, 201411 yr Author Unlike some I am not wanting to speed it up! I would like the option of lowering the cut off a bit.
May 6, 201411 yr As some have also posted I find the eco setting a waste of time and the jump to tour is too much for me as it means I have to pedal at 16 or more mph to stop using the battery. I too find that ECO is a waste of time, seems to pulse and do nothing unless I am going about 5mph. You don't have to pedal more than 15mph to stop using the battery, just switch it to off. I use the off button a lot on the flat and still move along at 15mph on a calm day, and 20 mph with a good tail wind. Rather that suggesting that someone hacks it, which I am sure is entirely possible, perhaps dealers could speak to Bosch and get it sorted? Whilst they are at it, they could also fix the walk function which is definately as waste of time. The dealers could then offer the required upgrade. Edited May 6, 201411 yr by SRS
May 6, 201411 yr With the new Nyon it is possible together with a smartphone to tune the motor support.
May 6, 201411 yr With the new Nyon it is possible together with a smartphone to tune the motor support. I've asked twice but nothing forthcoming http://www.pedelecs.co.uk/forum/threads/well-i-have-just-gone-and-done-it-kalkhoff-bs10-ordered-today.17290/page-8#post-213819

I too had trouble with the walk function, in fact I thought it didn't work at all, until I tried it with the bike in first gear...
May 6, 201411 yr Mine didn't work at all on the Grace, no problem at all on the Delite. I think it's how they are installed.
May 6, 201411 yr The walk is handy for me because I need to get the Rose over a couple of steps to reach where I store it. The 'speed' is dependent on the gear the bike is in - it is a crank drive, after all. One downside is the pedals creeping around under power which make them good shin scrapers. Easier for me because I have folding pedals on the Rose.
May 6, 201411 yr I have had two Bosch driven bikes, both walked on the level ok. On a steep hill, in any gear, they grind to a halt. No torque to speak of. The software is incorrectly written, I suspect. Not sure why Bosch would allow this but they have. I can live with it but fail to understand why I should have to.

It's exactly the same on the Panasonic crank units which first had this feature, no guts in walk alongside mode. It seems to be because the mode simply bypasses the pedal rotate function to run the motor. So with no torque applied through the pedals the power is at the minimum. These systems would need a redesign for the throttle to substitute the torque sensing and pedal rotation functions, meaning a switching function as well to get into that mode.
May 7, 201411 yr Author To be fair I never push mine, unless it's a hill I can't get up, in which case I would need a tow truck!

These systems would need a redesign for the throttle to substitute the torque sensing and pedal rotation functions, meaning a switching function as well to get into that mode. Surely it is a simple matter for the programmers to correct. When the walk button is held down for several seconds or more, turn the motor at "X" rpm with full torque available. The speed at which the bike moves dependant on gear selected at the time. When the button is released, stop power to the motor.
May 7, 201411 yr Surely it is a simple matter for the programmers to correct. It doesn't appear to be. This problem has existed on the Panasonic units optional walk-alongside throttle for more than a decade. If it were that simple, Panasonic or BikeTec* would have changed it by now. Software has it's limitations. *BikeTec of Switzerland first invented this mod for the Panasonic units, installing it on their Flyer e-bikes.

Ian, There has been a recent system update from Bosch, part of this update is the walk assist, it does up the anti a little. Not sure if this is more for the later Active & Performance lines. But is a simple install using my Bosch diagnostics system. All my bikes get free updates for the original purchaser, as you have one of my Haibikes, why not pop it over? We can perform a full system re-flash and zapp the new update onto yours? Would be a good chance to see the new store too? Oh and test the new coffee machine Regards Martin

May 7, 201411 yr Ha, you'd have to buy a bike from me first Belgium maybe on the cards for the future eh! Regards Martin

May 14, 201411 yr Thanks very much Martin, I"ll get up to you when I can. Ian, UPDATE - Flashed the new firmware onto a RC29 same as yours last week, no issues with compatibility. Unfortunately I hadn't had a chance to try the walk assist before I updated it, but it felt pretty responsive after the update... Regards Martin
