Re: Observed trials bike designing

Indeed. I should soon be receiving my first shipment of a new flywheel/clutched, brushless e-trials bike, claimed peak 10kw, around 42kg. Interesting, is it a new company? do you have a link? I would assume it does not have the standard trials 21"/18" wheels+tires, shock and fork, or 42kg...

Re: Observed trials bike designing

Indeed. That's funny about being able to restart if there's an e-trials in the class! Certainly doesn't happen that way here in Australia, nor in Germany from what I hear from a friend over there. I'm still not quite convinced that, " All of that can be mimicked by electric motor control progra...

Re: Observed trials bike designing

You have a point about using throttle, clutch and brake simultaneously. That does make it a bit tricky. Maybe a pushbutton switch on the brake lever itself so you move your finger over a centimeter or so to engage regen or not, then regen varies according to the first part of the lever movement or f...

Re: Observed trials bike designing

All the carbon is aftermarket add-on covers. EM currently use the Silixcon controller which is very flexible from what I've seen, but I'm not sure it's really capable of the sort of control and logic that might be ideal for trials. Once the likes of KTM make a serious push into electric GasGas trial...

Re: Observed trials bike designing

I started in the '70's, so yep cable clutch only back then. Glad not to have one now. I guess a lot of this comes down to the name of the game. For the most part Observed Trials is simply about who has the most skill at riding a motorbike over difficult terrain without putting their feet down. Addin...

Re: Observed trials bike designing

I haven't ridden a cable clutch in decades, don't think I'm that keen to do so! Are you talking electrically actuated mechanical clutch? Or an electronic non-mechanical clutch? I've never thought about an electrically actuated clutch. Could be intriguing, but I'm not sure how much it would really ac...

Re: Observed trials bike designing

Nice torque curve on the TXT 300. Very strong off the bottom. Looks like it was not yet jetted proper to make power as observed above the 6200 rpm break in the power plot. Overall looks to be a great power plant for the class. Unfortunately, with the limitations of the piston engine, it mostly reli...

Re: Observed trials bike designing

I love it! It is small, light & cute. Do the tires have a good grip on wet rock? The knobs seem a bit small. Are they made of a good compound? Tubeless or not? There are two tyres available (3, but the third is not a great option for any condition so we ignore it): Kenda Krusade 20 x 4 - quite ...

Re: Observed trials bike designing

The link you posted doesn't work as it puts the E-S site in front of it. Nice looking bike and a smart 2 speed gearbox! Any more info/specs on that box and maybe even a possibility to buy those seperately for home builders? It reminds me a bit of the Oset bikes: https://osetbikes.com/au/bikes/new-2...

Do you have any bnb pics of the 2-speed gearbox internals? No, I haven't pulled one apart yet. It's on my list of things to do! It's impressively compact - 10ml is the recommended amount of oil! I'm guessing it's straight spur gears inside from the sound and feel of it. There's no syncro, but it ch...

Re: Observed trials bike designing

I rather abandoned this thread and the time has come to explain why.

Now after something more than a year com...

Australian RCM certified 58.8V 10A charger sources?

I'm looking for a charger properly approved (not just a compliance mark randomly printed on a box!) to Australian RCM. 58.8V around the 10A area. Ideally it would be selectable between say 6 & 10A, but that's just a wish. I've seen a few at lower amperage, but nothing close to 10A so far. If any...

Re: Observed trials bike designing

Nice to have you back Guy.

I was thinking slew rate with the throttle stuff, but really I still think an electronic clutch is a very poor cousin to a "real" clutch.

Re: China to UK bike delivery

You are free to buy and import whatever you want - doesn't need to be CE'd to get it through the customs door at LHR. What you are not free to do is import stuff by the container load and resell it without CE... Is that based on knowledge of the rules and their application, or on observation of pra...

Not knowing myself what's involved over in the UK in doing this, my recommendation would be to talk to an customs/import broker that does this sort of thing.

Pay the taxes or customs fees and it should get delivered. Are you speaking from experience bringing such things into the UK, that customs don't care/check for CE compliance on one-off electrical goods imports?

Nice. I've never come across anyone with one of the eta bikes before - seen them on their website, that's all. What frame are you putting the new build into? From the fact you're considering putting a clutch in the new build I take it that you think it's still an advantage to have a clutch? I'm very...

Re: Trial riders need their clutch?

If you can afford it, buy the e-Pure Race. I certainly would if I could! As you say if you don't need it, you don't have to use it (clutch that is).

Re: Trial riders need their clutch?

That was totally tongue in cheek. When you start out on trials you'll be so busy learning new skills, whether the bike has a clutch or not will be the least of your concerns. Can you track stand at will on all sorts of terrain? Can you do full lock turns on different terrain - really full-lock, jam ...
