EM (Electric Motion)

Hi. I'm a user of Bertigo in South Korea. I'm asking you questions because I'm interested in the Electric Motion racing version. I wonder if there is a difference between the trial and the force of 300cc exhaust. There's no electric trials in South Korea. I have no choice but to access information on YouTube. I felt a little less powerful than the Slingshot engine 300cc. So I'm curious. Let me know.

Being new to trials bikes and coming from mountain bike background, how is best to set up the rear shock for my weight? At the minute it feels quite wallowy, should it have more rebound and is it a case of adjusting or buying a new spring for my weight (will any make of spring do or are they manufacturer dependent?) Cheers

Our club (XHG Tigers) will host a test day with Inch Perfect at our ground near Poole/Bournemouth. Date (unless everything goes wrong) is planned for 9th August. We will put a practice trial on as well so you can have a ride if you bring your own bike. I will update this thread as all the details finalise and the invitations for the test rides and trial go live. Hope to see a few of you there on the day.

I finally found a tidy 2016 EM at sensible money and have had a couple of plays on it now. Has to be said that I've barely ever ridden a modern trials bike so can't really compare it to anything newer than a mid 70s Bultaco Sherpa. However I have been really impressed so far. The bike is a lot better than me and better than I am ever likely to be at my age. There are 3 settings plus 2 maps which seem to control the throttle response for each, it is very mild on the lowest one with my near 14 stone on it. The middle setting with the fastest response map is my favourite so far. The highest setting makes more torque than any bike I've ever ridden right off the bo…

howdy ! I'm looking for someone that has gotten there e-pure race plated. Or suggestions on parts that work good with other bikes. what did yall use for head light set up? brake light? just looking for technical information from some one that hade done this already ! I've been riding dirty on the road and I'm sure I'm pushing my luck. There is just to many good loading docks and church parking lots not to. (loc. WA state) thanks!

My rear shock from my 2022 EPR is blown. I do not want to spend big bucks, so I am thinking rebuild Vs a used R16V? If so, is there a single size for the R16V?

Hey guys. My 2021 em escape r has stopped working. Ran it thru a pretty boring run up the mountain, came back down, everything was fine. The next day I go to start it and nothing. The battery engages, lanyard works, head display shows 98% and switching map to green light but their is zero power to the motor. Tried the reset cycle. Nothing. Even went as far as to replace the throttle control with a new domino throttle. Nothing. Has anyone dealt with this problem or does anyone know how the heck to fix this? Checked all connections, battery, fuse and everything's good.

I had a really good feel for my old (2021) bike with a 51T sprocket on it. Foolishly I left it on when I changed the bike, thinking it would be easy enough to get another one for my new (2023) bike. It's not. I can't find one anywhere. Does anyone one have one to sell, or know where I could get one? 51T preferred but I would go with 50T or 52T too.

The missus has just bought a 2021 Epure race. We had a nice day testing it yesterday and she seems keen enough to keep it and sell her Beta. The big yes-no decision is to ride it in a trial proper rather than just on a practice ground. We have just tried to sign up for a trial and the machine details page needs a CC and engine stroke. I remember that ACU said electric bikes can now be entered into the normal trials but the electric motor has neither a cc nor a stroke. What do other people put in? (Clearly you can make up nonsense if you want but the results will show Electric Motion 250cc or some drivel which is not really "right") She very kindly let me ri…

I'm asking the question first before i attempt to open it up. Is it possible to adjust the rotation of the throttle so the housing with the wire can point in a different position. I'm thinking this has been done to my throttle already as the open and closed positions differ from the other bike i have and this one will clash with the brake adjuster if i put it in the position i need it. Currently the closed position lines up with the clip on the housing body (blue line) whereas i need it to be the open position lining up with the clip so the main part of the housing points down rather than being where it is clashing with the brake lever. I hope this mak…

The write-ups are quite technical, but maybe some here will be interested. This link is the actual retrofit process: https://www.electricmotiontech.com/home/em-5-7/sx-controller-retrofit This link describes some preliminary work to familiarize myself with the SX controller: https://www.electricmotiontech.com/home/em-5-7/sx-controller-experiments

The S3 Hard Rock footpegs, in orange, work well with the orange accents on the ePure Race.

I've just come across an issue with my Domino throttle. After a small inversion that has left the throttle with a minor scar in the plastic (which may be a red herring), it has become sticky. Off the bike or with the clamp screws loose, it is fine. As soon as I start to tighten the clamp screws the self-closing disappears. I've tried packing the clamps with a thin piece of plastic: no good. I've tried tightening the clamp screws with the throttle off the handlebar and it works fine. Any ideas? I'm reluctant to take the throttle apart because of the return spring and the alignment of the gears, but that is looking like it will have to be my next move.

The map indicator light has stopped working on my '21 ePure Race. It became erratic a little while ago but then recovered. Now it's completely dead. I've cleaned the connector contacts and smeared with dielectric grease, but no joy. Has anyone else had the problem? How did you fix it?

Missus' 2021 epure race. I fitted a new chain and set it up like every other bike I have ever done - one finger gap between the spring adjuster and the swinging arm. Now it has a squeak - like a dry brake squeak which seems to come from the output sprocket at the motor end. We have both ridden it for a while but it is still there. Brake is fine and has not been touched, not had the back wheel out. No play in wheel bearings or gearbox output shaft as far as I can detect. I have backed the tension off a bit and the noise has gone. Squeak was in time with wheel rotations so it is somewhere or somehow related to that. My guess is a wheel bearing, but there is …

Hello everyone, New EM owner here, picked up a used 22 epure race couple weeks ago. What a fun bike, been having a blast with it. Although I have one issue that I cant figure out, went through this forum and haven’t seen a similar issue. When riding the bike for a bit randomly it will start to hold revs sort of similar to if the TKO is turned on even tho it is not on. If I hold in the clutch and release the throttle the revs will very slowly come back down very similar to a lean condition on a ICE bike. But With no clutch engaged the bike does not pull or want to inch forward. It will do this in all 3 maps. Then after a little while of this if I pull the kill tether …

Last weekend threw up a problem on my 2023 ePure Race. After about 2 hours of practice riding I returned to my car and parked up. A few minutes later I was going to take the lazy way out and ride the bike round in a circle to load up. However I couldn't, because every time I attached the lanyard I got the beeps that say "You've got some throttle on so I'm not going to let you select a map." I fiddled with the lanyard and the throttle, switched off and on, but nothing solved it so I pushed the bike. At least I was lucky it didn't do it at the far end of the site which would have left me with a 1 mile uphill push 😱.So today I have dug into things further. I tried switching …

I had never paid much attention to the breather tube on the clutch/primary drive case until today. While doing a bit of fettling I noticed that the oil was milky, so obviously I changed it. When I looked for a cause I spotted that the breather tube ended near the swing arm pivot. Well, last weekend I washed the bike after a trial by riding through some deepish water. The end of the tube would have been under water so I'm assuming it sucked up a bit of water then. I've no re-routed the pipe to finish near the spring top mount. Just a heads-up to anyone else to check it before they fill their clutch with mayonnaise. And on a different (but related) note, what was the d…

Hey Guys, In the past few days, my Electric Motion Trial has occasionally cut the throttle while riding. Now it doesn’t work at all. The kill switch still lights up, but there is no startup sound and the map switch doesn’t light up anymore. The battery provides about 50V and the battery relay clicks as expected. I also tried bypassing the kill switch, but it didn’t help. thanks!

I’m having an intermittent problem with my 2022 Epure Race. A couple of days ago, I started riding in blue mode with tick over on. Very quickly, it switched to green. Pushing the selector button again to blue, it again switched back to green when riding a short distance (it stayed in the same TKO mode). I rode back to the van, took off the covers, wiggling wires and harnesses did not trigger it. What did trigger it was hitting the right side of the motor with the palm of my hand. It was surprisingly easy to trigger it this way. Also, tilting the bike to the extreme left triggered it. Unfortunately, the problem stopped after about 15 minutes and I haven't been able t…
