Alright ya’ll, I think it’s time for a new project for me. I told myself I wouldn’t build any more boards this year, and also told my wife that… but a bike isn’t a board, right?
Not leaving esk8 or anything, just wanting something to commute with long distances. I was thinking about building myself a street legal dirt bike style bike. I want to take this thing on mountain bike trails occasionally.
I have NO IDEA where to start with this. Has anybody on here done a similar build or can point me to a forum of some sort? I was looking into Super73 but honestly, I’d rather have a custom build battery and have a project to work on.

“street legal” or street legal.

@Scepterr has a crazy build, have you seen his thread?
Endless Sphere has a lot of ebike stuff

What’s your budget? You could buy a Suron and upgrade it to 72v BAC 8000.
If you’re going full DIY, the Typhoon frame is a good starting point:

Thinking like 3-4k max on this project.
Actually, I’m really liking this and it can fit a big ass battery:

Surron bikes are definitely impressive and there’s a growing aftermarket.
A few links to check out:
ebikes.ca — parts, batteries, cycle analyst, motors, etc.
lunacycle.com — parts and bikes
hpcbikes.com — sweet domestic (US) ebikes
wattwagons.com — also really nice bikes from the States, but more commuter style. Also got some interesting electronics and motor control firmware.

I’d go full DIY. The BAC 8000, Typhoon frame, 72v battery, and something like a 10KW QS hub motor would fit into that budget. I haven’t built one yet, but I have been planning on it.

Would you take the Typhoon over the vortex?
Also, what do you think about this?

I think the Vortex would take a slightly larger budget. Perhaps you could get away with just spending the extra $300, and whatever the larger battery would cost, if you build the battery yourself. I’m not sure what that thing even holds. It’s enormous.

Here is what you can expect from a 72v/10kw + ebike: 72V Sur Ron Enduro | 🚀 Insane First Ride with 250% Power Increase 🚀 - YouTube
The Typhoon would give you a very similar build.
edit: a word

Just wondering what kind of range I can get with that much battery. Think the Typhoon would fit a battery capable of about 60 miles?

I guess they get about 45 to 60 miles, all depending on riding style , weight, and terrain.

I just noticed your question about the Kelly controller. I don’t know enough about them to recommend it, but I’m sure someone here or on Endless Sphere knows everything about them. I have heard of Kelly, and as far as I know, they make good controllers. You certainly don’t have to spend $1000 on an ESC.

Yeah at this point I’m wondering if it’ll be cheaper to do DIY, or just get the Surron-X lol

You will get a higher level of performance if you DIY. However, you could just get the Suron, and upgrade it later on down the road as needed. It’s a very nice starting platform.
