It is in a place that is all but impossible to see any part of without full and complete disassembly of the machine ! But yeah, agree it is unlikely to have been caused by a gentle side-over, though it happened to Rawnie and his suspension, despite his exceptionally careful riding and stairs avoidance ! So can't be ruled out. I'm just curious why it happened in the first place, what got it misaligned, I have no idea, just noticed it was stiff one day.

Well I guess the trolley handle hit something and now its hard to put down and I have to pull rather hard for it to come up. Not unusual event. Perhaps remove the trolley assembly. A visual inspection will likely identify where the bend is. Could then place in a vice, tighten, to straighten out. Or simply purchase a new trolley assembly and replace.

Popular Post Kutvis Posted January 21, 2023 Popular Post Share Posted January 21, 2023 (edited) Allright, here is a post generally to give rep @e-rides.eu! You guys rock! I charged my Master (V2) into 100% in train and then demoed it with another rider. The suspension was stiff and I tried it by jumping into air. The wheel died on landing and by testing we figured it was mobo. After swapping all the parts I can confirm this. There was no moisture in the mobo area, this was clearly a blown mosfet. E-rides worked with Begode to ship spare parts to me and gave new charging port module, it was a big hassle to get em and I was really worried as my batteries were 100%. It took 5 weeks which of 3,5 were waiting for parts, all were airmailed and came as fast as possible. In short: Thank you, e-rides.eu and Begode, it was professional work from both parties! <3 _________________________________ Now the results: I got V3+ (not sure if it was 3 or 4), it works *really* well! The "slack" earlier mentioned is completely gone and lights work in negative temperatures.

Cerbera Posted January 22, 2023 Share Posted January 22, 2023 (edited) Well, I had a fairly horrible time upgrading my Master to 'V3'. Satellite board went straight in there no problem, but charge board but was a right royal pain in the arse ! Begode had unhelpfully gunked the allen sockets in 2 out of 3 of the hex bolts holding it down, making getting those out a slow, painful and gradual process. Then tried to loosen my motherboard screws, but that was stuck down hard to the base by other means, and I didn't want to disconnect everything going to it so I tried to extract the old board around it, which took some time because of those massive capacitors being in the way, and squeeze the new one into the space. Got it stuck several times, but patient finagling won the day in the end, and eventually it went in, and seated OK. Damn awkward to get to those battery connectors with fingers - you almost have to do it by wiggling on the wires - I did not enjoy this process ! And I thought I had done it wrong when I didn't get any pop at all when I reconnected MB to charge board. But, no, she powered on fine, and balanced, my display and lights worked at -2 degrees C, and she is charging now, with no immediate signs of the magic smoke, so I think that went OK. Here's the bottom of the old board... versus the bottom the new one... Looks like we have slightly better soldering (except maybe that one pad above the top right brass spacer), and conformal coating everywhere on the new board, as opposed to just the battery connectors on the old one, and considerably more complex / populated layout.

Rawnei Posted January 26, 2023 Share Posted January 26, 2023 Anyone happen to find somewhere to buy replacement bushings and know exact dimensions? I know various bushings like it exists on AliExpress but don't feel like dismantling my wheel again and just want to buy some spares. 😁 Quote Link to comment Share on other sites More sharing options...

trailless Posted January 26, 2023 Share Posted January 26, 2023 Quick question, what's the highest amps you can charge the master? I think I remember it being 10amps. Quote Link to comment Share on other sites More sharing options...

Yes it is happy with 10 amps, and I think I read that was the max too. Of course rather better for the battery to do it at half that though if you don't need the speedy charges...

Popular Post Cerbera Posted January 30, 2023 Popular Post Share Posted January 30, 2023 (edited) Just back from another epic 30 mile ride on the Master, and thought I'd pop in to expound a little bit on the sheer levels of joy coming from that machine when it's working - I absolutely love it It's taken 3 bloody weeks of adjustments to get the Grizzlas perfectly placed, but perfectly placed they are, and wow, don't I know it !! It has just rolled me up the tallest hill in Hampshire (about 800 ft of elevation) in record quick time, over some horrendous terrain, and it has done it all faultlessly, mostly at 35 kph, regardless of the steepness of the hill, with a mainboard temp of just 10 degrees higher than ambient. I have been watching my tyre like a hawk for any sign of falling off as I get towards the higher speeds on this machine, and it looks absolutely dead straight to me, and has hung on without issue for 650 miles so far, but 35 kph does seem to be a sort of soft 'threshold', after which the wheel definitely starts feeling less stable, and a bit more wobbly, and harder to control. Is that normal ? Or a sign my tyre might be about to fall off if I push it much more ? Or is just that my little legs (think 2 bits of wet spaghetti hanging out of a drainpipe) are not yet up to the task of managing it ? I have not dared push it much past that threshold so far because of that low level instability, and feeling like wobbles might amplify if pushed. Carving gently certainly helps, but it still feels like it might be in some danger of taking flight if I give it the extra lean to push it to 50+... perhaps it is symptom of the stock tyre ? I am persevering with that for now, for its horrible over-lean has become less so with time (or at least more manageable now I am used to it), and I like its grippiness round the autumnal corners ! The way it deals with adverse camber adds a certain excitement But anyway, just wanted to pop in and do a post about the Master that wasn't all doom and gloom and ropey QC !!

Wow ok, makes one wonder why there's 7 revisions to begin with, like the latest charge board (c4) it's strongly recommended to swap to that one as the previous one causes problems with battery pack balancing, what problems does the previous 6 motherboards have? 🥴😧 1 1 Quote Link to comment Share on other sites More sharing options...
Cerbera Posted February 2, 2023 Share Posted February 2, 2023 (edited) Wow, that's a lot of revisions to STILL be making all this time later... I wonder what they are trying to fix with the ever-increasing amount of capacitors ? Anyway, quick diversion for another 1000 mile review, this time courtesy of Cameron Massie... Wonder which mainboard he has ?! He didn't mention swapping out the charge port board either... Edited February 2, 2023 by Cerbera Quote Link to comment Share on other sites More sharing options...

This one I was repairing the original controller/screen went together and mounted to the chassis like a sandwich. This new one has 4 mounting holes in completely different positions and had no way for me to mount the screen since the previous one had standoffs coming off the controller that mounted it. I was able to make it work by drilling/tapping new mounts to the chassis and partially disassemble the new controller "sandwich", use some shorter screws and nylon spacers to make my own standoffs for the screen. Was a lot of unnecessary work for a controller swap. Quote Link to comment Share on other sites More sharing options...

Jason is saying that Masters from eWheels with Litech BMS (which is what Cameron has) don’t need the charge port board. 1 Quote Link to comment Share on other sites More sharing options...
