So both? Why does it feel like it's only cadence? I've ridden few m510 bikes and they all feel like giving same assistance no matter how much pedal pressure.
Can this be tweaked in BESST?
If your bike has separate start button such as ew-sw100 or ew-sw300 those are notorious to have their cell flat. Cold weather and long storage does its thing to those tiny cells.
Display on your bike SC-E7000 does not have a cell in it. So it is not able to start the bike itself.
Well The battery on the start button ew-sw100 (or in display in other bikes) can be only charged by 2 ways:
1) plug it to computer separately(!) Via cable and a shimano diagnostic box. Go to e-tube. Maintenance tab. Charge.
Takes up to 4-5 hours to fully charge. this is mostly likely ever done...
Hardtail, defo
preferable shimano or bosch motor. Shimano brakes preferably, easy to bleed and very reliable.
For the fork Rockshox or fox or whatever your local shops are able service. (Suntour not recemmended)
Number of gears is not that important in a entry level bike. Shimano or sram...
On the right hand side that Internal di2 battery not needed. Yor ebike battery will power the derailleur. Since they are all connected. Actually I am not even sure if system accepts that battery since there alredy is a power source (ebike battery).
Also consider some display instead of...
You'll need a rear hub with (boost) trough axle. AFAIK there is no shimano hub available. What comes to mind is rohloff hubs but thats quite expensive.
Also your New rear wheel would need complete rebuilt.
Fitting a best would require you to take rear triangle apart. Possible.
And some...
First of all it is a very bad idea to pressure wash a ebike. Normal pressure washer has easily enough pressure to push water through the seals.
Sounds like you might have water inside the motor. A good shop might be able to open the motor let it dry and put it back to gather. I have repaired...
All I can say is that In service center they use only cable to update. Both shimano bosch and Fazua.
Also don't update if there is no problem. Or let service center do it while in yearly maintenance. any case you are not missing out if you do nor update.
Du-e7000 is compatible with the following: sc-e7000, sc-e6100, sc-e5000,
Or with an adapter cable:
Sc-e5003, sc-em800
E8000 motor is happy with almost anything.
Ep8 (also ep6 and ep5) is restricted to newer displays.
E6000 series uses only sc-e6000 or 6010 display.
I'll pull compatibility...
