The cantilever brake hole is at the top of the fork, so it should work fine for a 20".

I may be able to get away with just changing your username and removing the ' instead of deleting the account.

Congratulations, you found a bug in phpBB that is so elementary that i can only laugh at it. The issue is that you have an apostrophe, aka ' character in your username. This is preventing the database from writing your profile update. I would ditch this account and create a new one using a different...

Yup, 18fet and about 1.2kw-hr of 20C RC Lipo.

..i'd say in practice with a leaf (16lb hub ) and very light tires, i retained maybe 33% of my rear suspension's action. It wasn't as luxury smooth, but still better than not having suspension at all for sure. I didn't feel uncertain at high speeds, but yea. For offroad, a mid drive does shine. On t...

Get yourself a programmable controller. I like my infineon clones, but there's new and more interesting stuff out there today.

One that can do at least 40 amps would be ideal.. would give you room to experiment with higher power motors in the future.

You're welcome

Well yes, this is ping battery's design, both the cell layout, the choice of bms, how things seem to be wired, etc.. so i call it a ping battery.. or more technically, a ping battery clone.

Hey, glad you learned. That's what this place is all about.

The mid drive is an excellent route too, 3000w of power isn't a joke, it is likely just as powerful as the 45mm DD, but bike chain and derailleurs etc are rated at 500w, so they are sort of disposable maintenance items at those power levels. A downhill bike with very strong torque plates running a D...

Motorcycle wheels are going to be too wide and have much larger diameter axles, so you can forget that. A 22" bike rim ( some are sold for BMX purposes ) is said to take 18" motorcycle tires.. you could have about a 23 inch diameter at best.. so there is some geometry that will need to be ...

Actually i've been doing some reading.
The 1000w lightest.bike kit ( https://lightest.bike/#FEATURES ) is probably just the ticket for driving that mid drive.

Some emails have been sent.

It was OK at 21 mph (top speed) but I would not want to go a lot faster...I just don't feel very "connected" to it like I do when riding a bicycle. Yes, that whole center of gravity problem... your point of leverage over the vehicle is just too high. Basically the opposite of a semi recum...

2. You are probably right about the very large rear hub and more powerful controller being a better solution for my goals. However, I am in love with the idea of dual electric drive. Even if I put a larger rear hub on I would still feel compelled to add the mid drive as well. That would be more exp...

1) Oh i see. You're using low tire pressure to get suspension at the expense of added rolling friction. You will still hit a limit with that approach at some speed. I hit my limit at 30mph on 2.0" tires when hitting odd-shaped irregularities in the road that sent my wheels into the air and side...

Edit Update: Número tres gotas como una roca. It is already down to 2.6 volts :cry: What about a nominal 48 Volt 15S1P LiFePO4 battery ? I'm sorry to hear you learned a hard lesson about buying used batteries. I don't even sell my used batteries. Too much of a PITA shipping them or worry about what...

It worked pretty good in the 20" wheel on the rear of the Shuffle but did not have a temp sensor. Top speed was 21 mph on a fully charged 13s battery on it on level ground. I don't particularly care for riding a kick bike/scooter so I am selling it and going back to traditional style bicycles ...

Okay, since you want critique. You'll experience instant regret going beyond 35mph on a bike without full suspension. The second you have a wheel lift into the air from a bump and land in a place you don't expect, causing an emergency counter-correction, you'll regret your frame choice, because you ...

Some news.. I convinced maxaraya to ship me some of their chromoly suspension and non-suspension forks that they experimented with in early production. It's an honor to be able to get these very unique parts. image001.jpg They're oddballs. They both take 20" wheels, yet have brake bosses design...

A high end bike frame is often an ideal e-bike frame. http://neptronix.org/forumpics/hiryuu_spring.jpg This is an early 2000's Turner O2. One of the sturdiest yet lightest frames of it's age. It held up to 40-60mph duty and could have handled even more if the rear swingarm was longer. It was built t...

Thank you

Ah, the classic signalab BMS that drains it's power from 4 cells and eventually kills those. Must be a ping battery or an offshoot. Wonder how old it is.. With extensive balancing, you'll find out if it's worth keeping or not. It would need to be on a charger for days to accomplish that. I'd return ...

I actually find that offensive. I think that means you win the thread.

pps - xenforo is badass and you are going to frocking love it. I can't wait to get it rolling. I have never felt so motivated to do anything in my life. Right now i'm forcing myself to ear the yogurt on top so i can savor the fruit on the bottom. Seriously.

I made this meme years ago to see how many people i could offend at once.
I encourage you to coal roll the right way.

Ah, i don't want to get super technical and aim to be absolute #1. But i guarantee you there's going to be some low hanging fruit stuff that i don't see or even think about. That's mostly what i'd like to focus on, unless Justin wants to pony up for some really extensive SEO work. Thank you for tent...
