changing the seat angle is a thing
iām 99% sure this wonāt work but given how good motors and batteries/capacitors have gottenā¦is it feasible to create an āe-bikeā where pedaling charges a capacitor, which feeds a hub motor which drives the bike?
would you lose too much energy to various losses than you would through a normal bike drivetrain, after accounting for the savings listed below?
you could save the weight of all/most of the cassette/dangler(s), chain, chainring. cranks could be lighter because you donāt need to put out a ton of torque all at once. you could set the q factor however you wanted. i assume this would substantially improve suspension dynamics because no chain messing that stuff up. your rear wheel wouldnāt even have to be dished.
iām also roughly the least capable person on tarck to discuss this idea with any intelligence.
They sort of exist
great iām a genius
50% energy losses would hurt the cause a BIT though
When keeping it real goes wrong

We have absolutely built that
The recent versions of Shamu have the stokerās drivetrain totally self-contained, with a crankset driving a short length of chain to a 6-bolt sprocket on a 250W compact ebike hub motor. The āshifterā for the stoker is simply a twist throttle to set the wattage of the regenerative braking draw on the motor/generator. It is useful for helping the stoker keep themselves warm more than meaningfully charging the batteries.
The original version of Shamu pictured here has a stokerās drivetrain of:
- Stokerās Crankset
- 3 to 5 lengths of chain with a tensioner for boom length adjustments
- 7-speed internal gear hub drive sprocket
- Disc cog on the IGH hubshell as a jackshaft
- Chain from jackshaft cog to inner chainring on captainās cranks
- Trials freewheel on captainās driveside crankarm
- outer chainring to the rear wheel
- Rohloff in the rear wheel
Thereās also a trials freewheel on the NDS crankarm too, for a linkage to the kickstand that deploys when the captain pedals backwards

Road morph g. I wanted to like the turno urbo morph g but the larger barrel diameter makes finding a side by side bottle/pump holder difficult and for whatever reason it doesnāt have the extendable hose the road morph g does.
Either way get a G model for the gauge, though I donāt actually know how to read the road morph gauge.
Agreed that the gauge is best. Just kind of an approximate, but makes it so that you donāt need to squish-test your way between 35 and 45 psi.
I have a pair of these that I got years ago (from @Rent-to-own-Faxmachine?) back when they were the āBig Onesā. They were the tubed version and I think I flatted twice in 4 miles the first time I rode them. Very cool tires but 29x2.35" x 500ish grams is not good for the streets I ride on. Tubeless might work?
I have this one and it works well. Maybe even better because itās silver ROADIE TT Mini | Topeak
Has this been discussed? $32 in merica dollars

Not here but I like the idea. In my small & slammed bikes bar-bags never mount right. I think this would help.
I love that and Iāve been thinking about how to do something that simple for over a year and completely blown away by how perfect that is.

thatās cool but SQ what are the other options for burrito bag supports right now? Iāve seen a couple posted but canāt place them right now. Donāt need the low-profile jobber lol
Ah answering my own question because the above-linked company makes one of the ones I was thinking ofā¦
itās a reflector bracket that they didnāt put mounting holes in?

It would be nice if they said what itās made of
I agree
so I mined social medias and dug up this for you and only you:
