No problem, really, a few very very small jumps and some wheelies. Any hardtail would do anything on that video and a whole lot more besides. And the excuses for the URT design, pretty lame. I mean really, chain grow as an excuse?! No springs in their derailleurs?
Optibike ForumPro-pedal is platform damping to alleviate pedal induced "bobbing" i dont see why you'd need that on a URT anyway. Modern mountain bikes have little to no pedal feedback whether single pivot or linkage driven. Four bar perhaps have the worst, but that's not stopped Specialized selling it's Horst Link to everyone! My own Marin Wolf Ridge exhibits no bob, and i have a pro-pedal Fox RP23 shock on which i never use the Pro-Pedal lever at all.
Perhaps the bike suits you, but any claim of it to be a "mountain bike" are seriously hindered by the use of an out-dated suspension design no longer used on any mountain bike i'm aware of, and not even seen on "supermarket specials" very often anymore. All manufacturers abondoned URT because it simply didnt offer a good enough ride. All rider contact points need to be on the suspended part of the bike, as they are on all motorbikes, cars etc etc.
For me, i wouldnt accept that design on a £200 bike, let alone a £6000+ one.

The rant is a little hard to follow and the first paragraph is completely bogus, but it is true that unified rear triangles (URT) have fallen out of favor for generally good reasons.
The first paragraph is based on the laughable notion that "modern mountain bikes have little to no pedal feedback whether single pivot or linkage driven." I don't what this guy is smoking, but I want some! My riding style is completely different on a bike with suspension because of this issue. Overall, I love my full suspension bike, but pounding up a hill (without engaging lockout) evokes the image of wading through mashed potatoes (I'm old enough to remember the feel of pre-suspension MTBs). I guess I sympathize with the author's view of the pro-pedal feature, and rarely engage it when riding off road. On the other hand, it seems particularly well suited to road riding which is 90% of my time on the Optibike.
The second paragraph makes slightly more sense: It is true that the URT design has fallen out of favor, but the argument that "all rider contact points need to be on the suspended part of the bike" is weak. Notice that the Optibike's bottom bracket hangs almost directly below the pivot, transferring the weight on the pedals to the frame so that the rider, even when pedaling hard does not contribute very much to the unsprung weight. Even so, we should count about 1/5 of the weight off the riders feet and MBB as unsprung, which is never helpful. The real problem I have with the URT design is the tendnecy for the frame to drop under hard rear braking. My Optibike clearly suffers from this, and requires an especially smooth touch when braking hard in severe terrain. Four bar designs largely eliminate this effect.
The question for me is practical, not theoretical: Which available e-bike works best for my needs? If you can afford one, Opti
look awfully good in comparison with the rest of the field, with superior power, range, and - yes - handling. Besides which, Opti is the only choice is you want an off the shelf full suspension off road model.
Not so, the BikeTec Flyer X model is just that, and at similar high prices:Besides which, Opti is the only choice is you want an off the shelf full suspension off road model.
Yes. I looked at these as an alternative. But they were completely unresponsive to my enquiries and shipment to /from the US for the Optibike was a less challenging prospect than from Germany (or UK) .. Plus the language barrier and we fought the in the war etc.Not so, the BikeTec Flyer X model is just that, and at similar high prices:

Also SteveI would say its more like a high end MTB with a powerful motor as I haven't seen a moped on 26" bike wheels yet...unless you no different?
No war problem Tex, BikeTec are Swiss, albeit German-Swiss speaking.Yes. I looked at these as an alternative.

The stealth bomber is 50kgs!Should also point out that Stealth Bikes are Australian.
Full answer to all the questions arising in my post here:Does anyone know how much it costs to get such mopeds through the SVA? Or how much the annual insurance premium is? I expect the road fund licence is zero, based on emissions.
