Re: Rans Stratus - Recumbent

..honestly another aspect to consider is that without rear suspension, you're gonna have a bad time. I'd aim for a slower top speed. More like 30mph.

..at that point, the leaf 35mm is overkill.
The Shengyi SX2 or a 30mm DD starts to look a lot better at that point.

Re: Rans Stratus - Recumbent

I'd strongly recommend not going with a front motor, as ~80% of your weight is on the rear wheel. You will have severe issues with traction and funny steering on a bike with this design. Go rear, and try out a leafmotor 35mm "1500w" motor ( closer to 2000w rated in reality ). ps.. front di...

Oh yes and thanks to Dauntless, i have purchased what appears to be a pretty good book about optimizing aerodynamics:

Re: Lightweighting and aerodynamic optimization of a subcompact car.

i installed a K&N filter and it was a big mistake. Saw a drop in low end torque.. and a hypermiler spends a majority of their time at lower RPM.. it's causing me to shift later than usual. It's gotta go. I also found a rubber(?) stick on spoiler kit.. which i plan to use to make an underbody spo...

Re: LWB recumbent for long trips.

Wouldn't a bike that's half the weight or less be a better bike for uphill? why build a heavier one if you have poor power delivery ( creating more of an uphill problem ). There's a lot of recumbent bikes that can hold up to 300lbs out there. I see how movable pieces can be a test bed for ideas and ...

Re: Lightweighting and aerodynamic optimization of a subcompact car.

The firewall is fairly close to the strut towers on this car, so the upper strut bar didn't produce a world of difference, but it was noticeable. :) I'd certainly like a rear one.. and sway bars if i can get 'em. Oh yeah there's almost no suspension options for this car, but i do notice the weight l...

Cool. That would probably enable a very extreme fairing on the Cannondale at some point. Let me pocket that idea for now. :mrgreen:

If you want to ignore a user, you can use this option. But it will not allow you to block a moderator ( this isn't a smart thing to do anyway )

Re: LWB recumbent for long trips.

Looks pretty dangerous ( in a structural integrity way ), unaerodynamic, insanely heavy, and the opposite of stealthy.
Why did you chose to build a bike this way?

Re: Maxarya Ray 2 Semi Recumbent w/high efficiency mid drive

Thinking about this and what you said gives me a bit of pause because this area can have gusts of wind up to 80mph from all directions. more typical is 10-35mph. A typical fairing connected to the handlebars would easily produce some unwanted steering effects and be extremely dangerous. basically, i...

Happy to hear you chime in. Reinforcing the car for better cornering would mostly be done with strut bars, sway bars, etc.. nothing too extreme like full frame braces.

I've researched those additives very extensively and they appear to be safe for long-term use.

I had to hit the brakes in ...
