Re: How to built a 450CC RACE with similar weight power and torque like TACITA ?

it's fair but not quite. I know two electronics engineers to ask technical questions, that's not the problem. To give an example if I buy a burger from Burger King $ 1.5, why should I pay a cheesburger $ 2. For a cheesburger, I want to pay $ 1.6 or I go to the supermarket and for $ 0.5 I buy a chea...

Ok it's true Three time :flame: But which is the appropriated light and not expensive controller? I saw the votol em150, but one very good diy'er say that have no power acceptable for a dirtbike.

Re: Torp 11kW / 29kg mid drive electric free rider prototype

Well I hate to be the one to say this, but sometimes there are too much nay saying going on here.

Well a few years in and it was available for al...

Re: Cleveland CycleWerks USA Falcon electric motorcycle moped

Please, Even from a layman's perspective I see significant weaknesses in the frame construction. Why make an EV that tries to look like an ICE driven bike when it doesn't have any of the same limitations? I've built plenty of ugly ebikes that far outperform ICE's in real world use, so that part is ...

Within a month or two after the first bikes are shipped to customers I think we will start to see real world reviews, ride videos and possible side-by-side testing with other similar bikes, like sur ron, cake, otto bike mxr, revX and possible even neematic. Also some EV sites might be able to get in...

Re: Trial riders need their clutch?

...... This is in fact what many (most?) trials maneuvers require - rev up, then snap the throttle closed as you drop the clutch. It actually creates more "leap" than holding the throttle open. Holding the throttle open as/after you drop the clutch is also a recipe for disaster, as you loop out at ...

Re: E bike shivers before the ride

I know how it is, I am also getting e-bike shivers before riding a new build electric bike. For me it usually passes after 2-3 rides, if not I need to ride harder, faster and and just get more riding time. Within a week only the sweet memories of the shivers are left.

I got to agree with your analysis, for the power they where aiming for pedals will for many people be more of pain then a joy.

There was various ways to solve the torque arms. The 273 was even powering an all carbon fiber bike, think it was Luke's bike. Hm.
