Idaho legislators eyeing 2018 ebike proposal

Not good - it mirrors California's restrictive 20 mph, 3-class assisted. +severe penalties for tampering. Woe is me. Everytthing was peacchy until Pedego showed up. Then started whining about no regs to match their restrictive specs. Not to mention that the state rep behind the BS proposal is a 71 y...

Re: Game-Changer Electric Trike has it all, forget re-invent

... Delta trikes are not stable in comparison to tadpole versions, everything you can try will result in the same conclusions: Deltas are rolling and tadpoles are drifting. You'd be prudent to broaden your (miss) conceptions of 3-wheel dynamics. (perhaps a more in-depth search engine might help??.....

Re: material choice and shape for strongest?

Two issues to consider: 1: While structural aluminum will typically weigh 1/3 of steel (of comparable dimensions), it looses half its tensile strength (in the HAZ) when welded. Not a major factor with steel. 2: Have you given serious thought to weight distribution changes when adding passengers? Add...

Craftsman 40V 4Ah Packs $66

Apparently they're phasing these out - I snagged 4 on-the-shelf at my local Sears. IIRC, they have Sanyo cells - same as the 40v Ryobi. 10s2p (36V).

Re: Road bike fork, strong enough? add disc?

John, Are you sure that fork is Chromoly?... it should be stamped on the steer tube if it is. It obviously has a stamped formed crown, but does it have stamped or cast dropouts? Also, the weak spot on those forks (and highest bending forces) is usually at the crown race area on the steer tube (I've ...

Re: Framebuilders - how much trail do you use?

Papa, So should we shoot for 50/50 weight distribution with any LWB low bike? Is that only for equal traction and the effect on steering you mention above, or is there more? I've not been able to achieve 50f/50r on any LWB so can't speak from experience. I will say that the closer I get to 50/50, t...

... most have at least 180mm of tiller ... Is there a reason for this other than your experience? It's obvious that you can't have too much for the sake of maneuverability, but I've read the most desirable value is about 100mm and should never exceed 200mm. Depends.

Re: Framebuilders - how much trail do you use?

This is the bit that had me confused So to enhance self-centering and reduce sensitivity, the recumbent needs its 'stem' (a.k.a. tiller) extending rearward. And because of the presents of tiller (and fat rubber), I can reduce or eliminate trail entirely. Taken by itself, this is contrary to the phy...

Re: Framebuilders - how much trail do you use?

No John, it's obvious you do, in fact, know what 'tiller' is. Although both the boat and the recumbent share the same wording because of their design similarities, in reality, the purpose for each application is different. We both know that 'tiller' is essentially a lever used to navigate a boat - o...

Hey Papa! Is there any way to equate Under Seat Steering with "tiller". Does the steering rod or pulleys count as tiller length? Thanks in advance. otherDoc I don't think so Doc.

Here's a mobility scooter conversion I did about 2-3 years ago. The idea was slightly higher speeds (10-18 mph), and minimize weight. Everything forward of the rear axle assembly was scrapped and a new main frame was fabricated. The rear wheels were replaced with 3 x 10's and the front is now a 16" ...

Re: 30 MPH on 350 Watts?... Unassisted?

Love it! but when you put a wattmeter on it, you'll find the 350 watts is just a number, and more likely you are pulling at least 500 watts when going 30 mph. Shows the aero advantage that trike has though. An upright bike geared right would take more like 750 watts to be doing 30. I have WU so we'...
