Agreed. That's one of the big benefits of cheap bikes currently - cheap, available parts that work in a wide range of bikes. There's always been proprietary shit though, this particular tech isn't new in that regard.

You're right, but I think there are some other benefits to doing away with the chain. I have an E-mountain bike and between chain stretch, chain damage, and mud I go through 2 chains per season plus a couple trail-side repairs. Also, no chain means you can optimize pedal speed/torque for each individual rider, and keep it in the ideal range all the time regardless of bike speed. Essentially it offers a much wider power band than gears and a chain. You could also optimize crank length for clearance instead of torque. The front chainring is also a big point of contact on mountain bikes, removing that could improve clearance with the right design. I'd also be interested in the regenerative braking - if I go on an Enduro ride I'm cooking my brakes on much of the downhill, regen could save those and recharge the battery at the same time. Maybe regen could even lead to a smaller battery and save some weight.

Sure there are disadvantages - weight, complexity, efficiency, probably others too. I think with time those will improve though and this just might be a viable setup for certain use cases.

Legally speaking sure. I've never seen that enforced though so I wouldn't be particularly concerned about the legality of it.

The plugin is just called "git" it comes with ohmyzsh out of the box. You just have to enable it in your zshrc.

Are you able to fall back to normal git commands if you don't know the shortcuts? This sounds awesome until I can't remember the syntax to do something I don't do everyday.

Ohmyzsh with the git plugin is my fave - gaa & gcmsg "a commit" feels like the right level of verbosity for me.

Safety gear isn't a bad idea, but registration and insurance don't make sense to me - if I'm on a 100lb vehicle on a road where everyone else is in a 4000lb vehicle it doesn't make sense why I would need liability coverage. And I'm not damaging the roads the way cars/trucks do so it doesn't make any sense to me to pay anything to the state/country for registration.

You're not wrong but public transit here sucks. Every weekend I go to a friend's house - by car it is 1 hour every time. By train it is somewhere between 2.5 and 3 hours depending on delays. Public transport (even when poorly implemented) offers a great way to get in/out of medium to large cities, but isn't really ideal for trips from one rural area outside the city to another. What would be much more convenient would be if I could bring an ebike on the train with me. Most of the distance on this trip is covered by a 1h train ride, and it's just the busses on either end which are slow and unreliable. Unfortunately they don't allow electric bikes at all, and normal bikes are only allowed during certain hours.

My guy you shouldn't have visited New Jersey... In all seriousness though, this is at least partly satirical right? There are definitely some tough spots in America like most places, but when I went to Europe and Scandinavia it was about the same.

Ariel riders look pretty great! How is it to pedal? Geometry wise it looks like it would be hard to get much power out of pedaling it. I would seriously think about buying a used rider to steal the drive train out of though, seems like they have a nice powerful platform and lots of customization options on the aftermarket.

Awesome bike! I have an E-mountain bike and really enjoy it. For this application, I'm not sure if the mountain bike design will give me enough efficiency to hit the range I need. Maybe with narrower street tires and mostly locking out the suspension, but that removes most of the mountain bike advantages IMO.

Really appreciate your thorough answer! I'll definitely think about an electric motorcycle. IMO if I'm going to go through licensing, I might as well get something that goes full car speed.

I think you're right that battery capacity would be the biggest issue building out an ebike. That said, a big frame triangle can fit a lot of cells. Something like 3000Wh could probably get the job done. If I could get the bike aerodynamic enough to cruise on a 750w motor, then max range would be 3000/750=4 hours or 140 miles. Obviously won't hit that in real world conditions, but 70 would be possible.

I terms of legality and ethics, I totally agree about treating cyclists and pedestrians with respect - on my current ebike I keep it under 18MPH on bike paths and slow to pass others at a safe speed. My vision for this bike is more rural back roads near my house which are mostly empty but have an occasional car passing by. I'm not a big fan of laws generally. On that front I'll probably run a cracked controller with a toggle so if I get pulled over I can put it back in legal mode with a keypad sequence. Slap some aliexpress "250 watt" and "class 2" stickers on it and trust that the local cops are few and otherwise occupied. Where I live folks rip illegal dirt bikes and ATVs on public roads with impunity so I can't imagine this being a big problem.

 

I live in the USA and if I want to get rid of my car I would need to be able to cover 70 miles round trip with moderate exercise in a reasonable amount of time. I think if I could cruise at 35MPH (56 KMH) that would be enough to make the switch.

It may be stupid, but I'd like to try to avoid an electric motorcycle - those need insurance, registration fees, real parking spaces, and a special license. Also, I enjoy getting some activity while riding. FWIW I'm not worried about legality, but I do plan to stay off bike paths/sidewalks to avoid endangering pedestrians and other cyclists.

My idea so far is to start with a gravel bike frame for aerodynamics, efficiency, and sturdiness in case of a pothole or rogue curb. From there I'm thinking about a 1500w hub motor, dual batteries, higher gears, bigger brakes, and permanent lights for visibility. Also a good helmet of course, crashing at that speed can be pretty bad.

Has anyone done something like this and had it go well/poorly? Anything I'm clearly missing in my plan? Also feel free to tell me if I'm an idiot, but I already know that bit.
