I rode the economy version of this trials bike: ...several times at Sooner Cup, and watched others ride the bike. The economy model looks like the same core design, but the top model has the pricey suspension. The one I rode had economy Olle forks that topped out sometimes on fast unweights. I heard the top model has a clutch lever that is an on-off switch. You can roll the 'throttle' on and release the clutch for more impulse. The economy model has nothing there, so it disturbs the mind. Nowhere for the left index finger to rest! I was struck riding the bike that the 'throttle' was much more controllable than I expected. I've watched a lot of kids having problems with whiskey throttle with their electrics, and I expected the same. From the first few motor pulses of cracking the 'throttle' open (OK, I'll stop with the quotes), to being wicked wide open, I found the bike will give you what you want, precisely. To 'start' the bike you snick a rocker switch under a top frame rail to on. You year a click and an LED light comes on near the switch. Then there is an Off-Run-Off switch on the bars. That's it. Nothing whirs or runs until you crack the throttle, and then all you have is individual motor pulses that tack tack tack... the bike moves, then the pulses build to in interesting tone as you open the throttle. There is a 2-map switch on the bars. I found the tame map to be fairly useless, as did a Novice-level rider, as it felt delayed and weak. The quicker map gives you a more direct feel to throttle response. Battery life was about 4 hours. Plenty for an event. I could ride this thing and compete on it very comfortably up to upper-mid-level classes. For higher classes I'd want an engine and a clutch. I must say I was quite impressed, however. For most riding the EM was very adequate. The handling was neutral and good, and every worked as it should. All test riders came back saying they were positively impressed except one, but he rode the loop with the map switch set to weenie mode. My wife rode the bike. She is used to a Beta 80. She said the lack of a clutch made her feel a little insecure, but my observation of her riding made me think with a little reprogramming time she may prefer the electric. No starting issues at all for her with an electric. For quiet stealth riding, the electrics are the kings of the world! Imagine night riding into remote areas with LED lights! No one goes into most remote areas at night. Other than light splash seen at a distance, one would be indistinguishable from night hikers. Nice is being able to hear much better what's going on around you. If you stop and balance there is no noise at all. Summer riding in the cool night, anyone? Night events on a lot right in the city? The possibilities are intriguing! EM bikes are made in France in very low production quantities. Even the economy model is quite expensive at around $10k I think. Ryan Young said he sells every one he gets in and rarely has a demo top model available because they get snapped up. With better suspension and some semblance of a 'clutch', the EM be a great second-type bike with which to explore a whole new world. http://www.electric-motion.fr/ I know few other details, but these electrics are definitely getting my attention.
