Check your speed sensor is working correctly and / or the clearnance distance you have to the magnet, you need at a minimum about 10mm clearance and the centre of the magnet is positioned not where the attaching bolt section is, but about 1/2 way along that outer section that leads to the entry...
The last couple of volts only equates to about 10% of the total Wh available. Bafang obviously don’t want to stress their batteries life span by going down to completely emptying the cells. It makes good commercial sense when a large percentage of their clients are commuters rather than a few...
Sure agree with that. Reds are fine for us but as we are a geriatric bunch, riding 4 continuos days is tough on the bodies, its nice to have a couple of days of easier stuff interspersed with BPW. :)
Thanks, the Gap loop is on my list to do but not this trip. Looking for loops close to Methyr rather than having to drive too far, its a chill out trip as such.
Its interesting that the Llwyn - Onn reservoir is just one ridge over from the Gap route with paths over, any idea from anyone just...
We are staying for a few days at Methyr Tydfil near the Llwyn - Onn reservoir, to ride BPW and some other riding. Can anyone recommend any 2 - 3 hour loops around the area as filler in for the days we are not at BPW. Looking for chill out style rides rather than epic adventures.
Thanks.
Does anyone have any GPX files of XC rides outside of BPW or have a link where we can find some ?
We are planning to stay down there for a few days in a few weeks and looking for rides out of the BPW area that are more XC orientated. Looking for circa 20 -30 miles routes max about 1500m.
Thanks
The older DP242 display used to give accurate % right down to 1% for the 52 volts, the newer DP245 doesn't for some reason. On my M510 it works out about a display of 40% is around the 46 volt shut off ( which is 3.2 volts a cell, the motor knows you started with a 52 volt battery ). On the...
Be careful with what appears a very limited knowledge of batteries. Can I suggest perhaps doing quite a bit of research into battery building before proceding down this route. Little things like parallel charging with approx. voltages can lead to some serious problems. Choosing the wrong cell...
Does the display register the correct speed when spinning the rear wheel on a stand. I think the motor has to see speed registered to continue supplying drive ?
Thanks for the reply Dado. This high cutoff is stopping me using nearly 100Wh of a 800Wh battery. In 3 years the battery technology will have moved on so far that my 800Wh battery will be redundant. How many Ebikes batteries are going to be charged 1000 times a year ( typical cells are based on...
I've had a bit of a realisation that the M510 controllers at 52 volts know that it is a 52 volt battery and will shut off the motor at 46 volts on the battery even without any CAN signals ( home built battery ). Thats 3.2 volts a cell. My old M600 motor used to run the battery fully down to...
Sounds very
Sounds very much like a connector problem, check the usual culprits of the display connectors not being pushed in far enough and down at the motor end, also make sure the connectors are pushed firmly into the correct place.
Voltage levels changing could also be the battery to...
This guy might be the guy to ask. Bit further on than the French / Spanish border but maybe worth the extra couple of hours driving.

For every rider who hates the over run there are an equal number who ride technical trails that like it. I think your perception that " everyone" hates over run maybe a bit flawed.
In my case I have learnt to use it to advantage and can now climb up over extended rough steep uphill short bursts...
Thanks. Yes looked at his mods and from my engineering experience, its a good mod but.
I've just pulled my M600 engine down and largely for the really harsh environment of the UK winters where I'm riding in wet, muddy, sandy, rock strewn conditions for possibly 6 months of the year, for the 3K...
Not actually sure as I bought it in and stuck it on the shelf as a spare as I had eyesight problems with the older DPC242, I'll have a look in the next couple of days.
I think Neeko had a vid of it but I can only find the short clip Quick Peak of the DZ41 display (CANBus) hooked up to the...
