EM (Electric Motion)

I have recently purchased one new and quite surprised there is no manual or anything with it so did anyone else get one with theirs?

Is it possible to charge an EM off an inverter from a car? Anyone know specification of the charger? Is there an optional charger that might be plugged into a running vehicle?

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…

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…

I'm 10 rides in on my 2023 EM pure race. I live and ride the steep trail geography in the mountains. However, I'm already needing more power for certain features (very, very steep rock pitches). The EM can't maintain the velocity required - it slows (bogs) on these few features. I thought to change the front and rear sprocket ratio to gain low end power, but on evaluation its already fitted with an 11 tooth front and 57 tooth rear - does this leave anywhere to go on this front? Can anyone think of a way to coax more grunt out of the bike? It feels like a way heaver flywheel might do something - if I could spool it up but I don't think that's really an option either. Than…

anyi one whith a 2023 has try it? https://play.google.com/store/apps/details?id=com.em.emconnect you need to scan the qr code of the owner manual or a sticker on the right side of the bike

Has anyone got any experience of converting an existing petrol bike to electric? Any advice or pointers would be greatly appreciated

Hi, I'm considering buing an electric motion trials bike but can't justify the money for a new one. I've seen a 2018 EM sport one for sale but can't find out all the information i'd like on it. What type of clutch is it, a mechanical one like an normal bike? How can i tell the state of the batteries and are they easy available if they need replacing?

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

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

My controller seems to be jammed on the reset function. I've renewed the switch which hasn't cured it. Any ideas what to do next?

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.

Hi I have a specialist looking at my battery however he would like a schematic of the wiring inside a EM 5.7 battery. I'm getting conflicting information on the exact makeup of the battery, has the battery 13 cells only, 13 cells with a 14th cell that controls the relay or 14 X 4V cells with the 1st cell also controlling the relay? This Battery has had a Neptune BMS fitted that although very clever it does keep on tripping the solenoid regardless off the multitude of settings and parameters I have tried to resolve the issue. I have decided to have a more basic BMS fitted but unfortunately the wiring is a bit hit and miss at the moment hence the request for a detailed sche…

My old 21 Escape R apparently has had some throttle damage. I remember reading here someplace that a replacement (Domino?) has been used with good results and the quality was better (stock was not great). I cannot find it, please help if anyone knows. (Note, I no longer own the bike, just helping owner out). Mark

2023 Epure Race, manual pgs 33 and 35 and 36, TKO and TC Traction control do not seem to work, even after reset. (The FRB, motor braking works) EM Connect, the app, I can't get through the screen to enter a code. I have worked with the dealer, who is sending me a switch and diagnostic cable. Dealer says the feature is new and optional, it doesn't know. I have emailed EM France without any reply on these three issues. Is there something the dealer and I are missing? Thank you. John

Hello everyone, I purchased a new 2023 EPure Race trails bike about a month ago. This is my first trails bike so I am pretty excited about it. Last week I rode the bike with zero mechanical issues. A few days later, I rode the bike again, but this time as soon as I gave it throttle the clutch was slipping, and it was very apparent. The slightest incline, causes the bike to struggle and I can just hear the motor wind up but very little power. I have ridden dirt bikes, all my life, but are new to trials. I have not been beating on the bike hard or popping clutch at high RPMs a lot. I do the occasional clutch pop getting over down trees but that’s about it. I checked th…

the battery life seems to be getting very good with these and i love the idea of practicing in the backyard without annoying anyone. the only issue i could see is if wanting to ride all day the battery would eventually go, and it would be expensive to buy a second one. but seems you can recharge them to 80% capacity very quickly so would be an interesting idea to hook it up to a solar panel over the lunch break. :-)

I have now been riding an EM for 4 years but there are still things I think could be done better, and I'm wondering if they are possible. I would like to have a little bit of "engine braking" when the throttle is closed. I quite like the idea of the "Finger Throttle" on this page, https://www.electricmotiontech.com/home/em-epure-race/regen-experiments. If I understand correctly, this would be a straight bolt-on if I could get the right finger throttle. It could replace the present PRB-R (2023 bike) and the 0.8 volt would provide the engine braking. Right? I only ever use green and blue maps so I would like to get rid of the red map so that the sequence would b…

I want my 2024 sport to sound like Toni's 4 stroke torquer since I've been inundated with his impossible antics on Instagram. I love the one finger diaphragm clutch but to really get the feel of motor /flywheel inertia, I want a low frequency pop instead of the 'zing' sound which is mainly due to gear train noise. So I took a cheap 12VDC car alarm out of the trash and tapped it across two random AC motor phase leads, just for giggles. And predictably, it first smoked a little, probably the 50+ volts into 12 V circuit thing, no surprise. But then it kept working and would produce an ugly growly sound proportional to RPM. I'm not an Electrical Engineer but no doubt so…
