Remember if you do anything such as a third party app to mess with the motor and you brick it……you are out of luck.

I got the motor from Shimano USA via COMMENCAL in Colorado. Absolute bikes in Sedona did the install and the info I wrote above is based on what the technician was told when he called Shimano USA. My best guess is that you might need to be at some kind of bike store in USA with a technician...

Exactly!! I might send him my original motor that I recently replaced with a new motor bought from Shimano USA

There is a Shimano Facebook group with a guy who repairs Shimano motors and has a pretty large stockpile of parts.

Actually you don’t need to violate the warrenty if the motor was obtained directly from Shimano. But you need to be present at a certified Shimano dealer with expertise in firmware to get USA not eu class I installed ( 20 mph s 15 mph. ). I learned this the hard way. I’m riding with the eu set...

I used to think of it your way. I contacted the Scotsman who produced a detailed tear down and rebuild of an e8000 motor and he demurred on taking on a repair. Then I located a place in the SE USA who had the actual bearings but would attempt to rebuilt for 2/3 the price of a new motor but no...

I was off my ebike for some spine surgery. Went for a ride 8 weeks post op in on and off heavy rain and hail on the clementine loop in Auburn,CA. IT WAS ESPECIALLY squirrelly with the motor threatening to seize at any moment. Thinking it was time for a Change I got it all prepared to ship to...

So I actually bought a brand new in the original box e8000 motor. COMMENCAL USA ordered it for me and shipped it to my home $1200. So now I’m still riding the original clanker but keep to motor with me. If and when it locks up etc I’m gonna to put it all in a box and send it to COMMENCAL to...

So my 2018 e 8000 on my meta power is starting to clank after watching the Scottsman’s disassembly on YouTube, my original motor needs to probably get some new bearings and lube which of course can’t happen without a right to repair attitude from Shimano. so I decided to buy a second motor...

Serious numbers!!

There is a great YouTube on the bearing replacement unfortunately Shimano doesn’t respect the right to repair ethos.

My e8000 motor on my 2018 COMMENCAL is making a variety of noises at 4500 miles. It’s most likely needing a mechanical overhaul with bearings and lube. Supposedly Shimano USA will have fresh e8000 motors stocked around October. While I’m thinking second ebike, I’m going for a new motor at $1000...

I'm revisiting this post. Wouldn't be reasonable to assume that a 300-400 watt inverter would be sufficient to use the stock Shimano charger to recharge their batts ?

Does the plate behind also carry a negative charge or is it isolated from the brass?

As I recall the plate behind the neg electrode was blocking access from the rear.

Can you snap a picture of the outside of the connector after your fabrication? What you did is exactly what I was contemplating to do.

i have 3700 miles on my e8000 commencal meta. the battery to bike connector of the mt e8010 cracked and shimano offers no spare parts for repair of an otherwise ok battery. so now i own 2 other batts. ive replaced the speed sensor once and the mode selector on the left perch twice. the motor...

fyi: as expected shimano blew me off. not willing, caring to, etc,etc to help me out. all i wanted was to purchase the part. why should they give a hoot.

1. Shimano doesn't stand squarely behind it's e bike problems. My battery saga is proof enough. The part of the negative battery lead copper hat plugs to the metal prongs cracked and those slugs don't even stock a $5 part. 2. Never update e8000 firmware.

Your solution is radical but reasonable. I sent a repair request to Shimano warrenty and expect it to be turned down. I'm curious if other brands such as Bosch have these kinds of issues. I was going to stick with shamomif I ever bought a.sexond ebike but now I'm wondering if that's a wise...
