A+ car bike combo.
needs a foldable ramp that you ride up from behind
5lb over the weight limit for this rack, so I didnāt get on the freeway
itās kind of a clean and jerk to get a bike up here lol
Just because it didnāt occur to me the first time I had an e-bike Iāll mention: removing the battery definitely helps!
Maybe I should be in here? I dunno!
Anyway, rode off my street for the first time this evening and immediately grenaded the quick link on the⦠8 speed KMC chain?!
I threw on a campy 10 from my parts bin and now it is skipping lol. I think that the gears and chain need to mesh.
But also: ebike chains exist. Should I buy an ebike chain?
I canāt tell you whether or not to buy an ebike chain, but I am still using whatever 10s chain Iām assuming came stock on my big dummy. I havenāt had any issues with it, but Iām also not hooning around on my dad bike. Chain has lasted a weirdly long time on this bike too, previous owner miles + ~2000 acoustic miles + ~2500 electric middrive miles.
I think if you are going to max out the assist it might make sense to get an ebike chain but otherwise I wouldnāt worry about it
Ok, yeah I assumed regular olā chains were fine.
Next step is to figure out what chainring/cog ratio Iām supposed to be running with this enviolo hub. The previous owner messed around with those and I donāt know what should be on here.
How do you like the hub?
For a bike like this itās fine. I liked the way that this bike felt with a derailleur more, but a bike mechanic friend told me that Iād shred a cassette in like 500 miles. The decrease in maintenance I guess is worthwhile. Not riding this for crispness or acceleration or whatever. If anything makes me swap this out for a derailleur drivetrain, itāll be the goddamn grip shift. I wish someone made a fancy grip shift for this system.
i bet you could growtac it!
thatās just drop bar aināt it
yeah, but
Just going to pop in and say that Biker Boyz was just me and one other dude tonight, so I loaned him my wifeās REI bike and I took my E-Dummy and we rode to a brewery that is a little further and hillier than we usually do and it was quite nice
Watched the 2nd half of this the other day:
The way he build his ācarā is pretty lol and theoretically there isnāt anything too crazy about this but I thought it was cool. It pretty much works even when the vehicle is constructed in the dumbest way possible. Like if you had a pedal-assisted tadpole trike with an aero fairing, how large of a solar array would you need to keep one of those things rolling along at 20-25mph in perpetuity? Weather permitting of course.
I believe we have a tarcker who did solar vehicle competitions at uni
hello
modern good solar cells? Not a lot. 2023 World Solar Challenge cars were limited to 4sqm of terrestrial-grade solar cells (no multi-junction gallium arsinide bullshit), and averaged 45-55mph across the outback for 5 days straight, no pedal assist needed.
ballparking: power goes with V^3, so if you only wanna go half as fast, you only need 1/8th as much power. So with a streamlined velomobile, you should really only need half a square meter of good, 25%+ efficient solar cells to cruise at 20-25mph all day.
How much does weight change the equation here? Iām not personally interested in building such a thing but an e-touring bicycle with a solar trailer would be a pretty cool thing under some circumstances, but Iāve never looked at those velomobiles and thought āyeah I want to be in one of those all day for a weekā lol
it matters, how much it matters depends on how good your tires are. with low rolling resistance tires it wonāt matter as much. but rolling resistance is generally pretty poorly understood, imho itās often the achilles heel of these youtuber solar cars.
with an un-faired upright bike, aero drag would surely be the dominant force
So, Iāve placed an order for a bike but it doesnāt come with lights. It has the Bosch cargo motor. Anything specific I should look at or just pick something from B&M or Supernova?
Look for an ebike compatible light.
I believe different motor brands have different plug adapters but Iām not sure how that works tbh. I assume that either the light or the bike will come with what you need, esp. for a common motor like a Bosch.
