What kind of capacity from your LFP battery? Is it diy built?
I did one in the spring 16S with 25Ah cells and it's been amazing since. Only problem is it's a bit too big to fit anywhere I'd like it to. I have to mount it on a rear rack
I am using 3x 12v 185wh batteries in series. Realistically I can count on around 500wh. They are only 3 lbs each and fit neatly within the frame of the mtb. I don't like having them up on the rear rack, they tend to make the tail of the bike wag a bit compared to low and centered.
I have a big commute and in the (Canadian) winter my old 750Wh was sometimes not up to the task. So I went wildly over the top and built a huge cap battery. I never need to worry now
Unusual for ebikes to use lifepo as they are much larger and heavier than standard lithium ion. Especially in cylindrical formats that are needed to make bike friendly battery shapes.
Agree, they each have benefits. I broke a chain with my mid drive in winter and really wished I had the redundancy of a hub motor. Also, many many bikes cannot easily fit a mid drive retrofit though I think the diy community isn't as large these days given the variety of ebikes available
Regen braking is a thing for ebikes. I can't speak to OEM ebikes, but check out grin at ebikes.ca. They offer all the parts.
There are some cool features too like setting a speed limit after which Regen activates, so coasting down a hill will recharge you and add resistance to keep you at a safe speed.
The caveat is it doesn't make sense on mid drives because they freewheel when coasting
It's interesting whenever this comes up on Reddit and there are a hundred comments parroting how dangerous this is, but on closer inspection you can see the comments cannot discriminate between important details - eg. talking about how dangerous extension springs are, having no clue that they are different than torsion springs. Always fun to see how many people will pretend they have knowledge on a subject they have no experience in.

And every time a similar post or question is made the same responses are parroted again.
I’ve read so much Reddit in college that I would play a game where id try to guess what the top voted comments would say. After a while it becomes tiring to read the same things over and over again.
Something I've noticed is that, when under the guise of safety/"don't do this thing", netizens seem to have few inhibitions sharing information from topics they barely understand or have experience in. Some caution is always good, but I feel like people are too comfortable using it as an excuse for sharing unsubstantiated information as fact.
Chains usually have no service interval, so at the outset they seem cheaper and more reliable. But the unfortunate reality is they still fail, or something related to keeping them on fails, you just live in a false sense of security for a few 10's of thousands of km more
And since they're not meant to be serviced on a regular interval, they're designed that way too. A timing chain might be over four times the expense to replace when compared to a timing belt, but possibly without actually lasting over four times long.
I share your disdain for drums. Only issue is every four wheel disc vehicle I own still has a drum for the parking brake. Except these days they're electronic and need a scan tool to release them and get the rotor off!
Electronic drum brakes sound like my personal version of hell. I knew of the existence of electronic parking brakes, but hadn't realized that any car would be silly enough to need a scan tool to release it for service.
> Waymo employed around 2,500 employees at the start of the year, according to reports. More than 200 were axed in the two layoff rounds earlier this year, but the number of remaining Waymo staffers following this cut is unclear.
