EM (Electric Motion)

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

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

Thought I'd share my experience of the EM5.7 I bought last autumn. First off a little background. I'm a long-time road bike rider who switched to dirt bikes a few years back because (a) exciting riding on roads is too d**m dangerous ( track days here in southern Germany were too time consuming and expensive © dirt biking I can do together with my kids (they're only young once). Before the EM my only exprience of trials was the odd borrowed ride in a gravel pit or w/e courses. My main ride is a 350 ktm sports enduro (mostly ridden on local motocross tracks) but my kids (also riding mx) started with an OSET and continue to love riding their electric trials bikes. Jea…

Where will I be able to get a new rear mudguard in the UK? Inch Perfect don't have any on their site but guess it has to be possible to buy one somewhere.

I just bought a lightly used 2016 EM Sport 5.7. I have very little trials experience; had a Cota 349 sidecar for a while. I had a hard time getting passengers (they kept running away screaming). So I took off the hack and rode it solo a bit. Did a few vintage events and got hooked but never really liked the bike. Life got in the way and I sold the rig. I'm about to retire and this became available just as I thinned the herd (sold an FZ-09). So far I love the convenience and simplicity of electric. I'm looking forward to riding an event next year.

The propstand on the ePure holds the bike too upright so I have found I have to search out a low spot in the ground to place the stand on when parking up. It's a bit of a pain in the posterior so I went looking for a solution. Now I've put a washer under the inboard fixing to the swinging arm. It seems to be better in the garage, so I'm hopeful for the trial tomorrow. If it turns out to be better but not enough, I'll try two washers but that will need a slightly longer screw as there isn't a lot of thread engagement. Tyre clearance is also extremely tight. I don't know what can be done about the spring/tyre clearance but I've cut off the redundant spring lug and that…

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…

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…

Should the front disc have play in it or be solid? I could hear a noise from the front wheel area and found the disc has play in it, the bolts are tight but it looks like some kind of washer has degraded maybe allowing side to side play on the disc. I'm thinking it shouldnt move but always best to check lol and were can i get replacement washers form if it these that are the issue. I have two 2021 bikes and its the same on both

The manual says "If you want to store the battery pack, you have to take some measures..." Before storage, the battery pack must be charged; Be sure 100% the battery pack is switched off; Recharge the battery pack every 4 week, even it is not used; Do not store the battery pack under 10°C (50F) or over 40°C (104F); Do not store the battery pack in wet atmosphere; Do not store the battery pack exposed to the sun; Remove the battery pack if necessary. note the "if" - I wonder if that is mandatory, highly recommended, or truly optional. Does anyone leave their bike over the winter in the garage, below 50F, without storing the battery?

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…

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

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…

Just bought a 2024 Sport model and really enjoying it. Certainly a big adjustment from my Sherco 250. This was my very first try right out of the crate last week... I was fooling around with the clutch and winding it up for no reason. This was this week (snow is gone) - a lot quieter you can hear the sound of the X11s on the driveway

I ride classic trials in AHRMA and mountain bike. I live on acreage and I have been building a lot of technical trials section and mountain bike trails. I have a TL125 and a Sherpa T. I find that the motorcycles don't handle the tight downhill trails as well as my mountain bike. The feel too big. I am looking for an electric trials bike that can ride my trails. Do any of you with experience think that the Oset 24 might be a better fit than an EM? I have seen video of it ridden by adults and it looks about the same size as a mountain bike. I thought it would be easier to move around and lift in tight sections.

I could be in the market for a electric trials bike. like the EM 5.7 , is there any upgrades from the 2017, is the 2018 out yet ?. EM web site or Facebook page don't give much new info. I do like what I'm hearing on the new Mecatecno T18. any info from you electric bike guys out there.

I've just bought an ex-school 2023 ePure Race from Inch Perfect. It looks beautiful and I'm generally very happy with it, but like any secondhand (or even new) bike there are one or two things to sort out. I'm not impressed with the way the TKO switch is mounted. It's awkwardly inaccessible and is mounted on a curved bit of frame tube so it doesn't fit well. As a consequence mud and water can get into the back of the switch, which has happened. I'm thinking of putting it on the handlebars instead. Has anyone else tried that? It would require a two wire extension about 1 metre long (I haven't measured it yet) with male and female connectors. I can find pre-wired connect…

Not long had my 2022 ePure and have just arrived in Spain to give it a go, somewhat different to my back garden. I have the impression that the bike rolls on somewhat with the throttle closed, whereas in the garden, albeit very flat, I felt as though it always stopped. Is this normal? I did a decoder reset after being advised by a very useful YouTube video but it continues, and any sort of downslope requires braking. Second question is that I have an electric car and charge this with the public charge points some of which have a normal two pin socket, (I live in France), which my charger would fit. Would it be a safe way to recharge? Thanks.
