Re: EXTREMO - Scratch built 7kW billet frame scooter

correct. this boy weight 50kg so the folding system can just help to better load in a car - non need to make thing too fancy Seems like it is more of a permanent system which can be partially disassembled so I can fold ... rather than a folding mechanism. This is such a better option for my use cas...

BTW, looking at the pictures again it looks like you put the tires on the wrong direction.

Re: EXTREMO - Scratch built 7kW billet frame scooter

Impressive work. One the one hand it looks narrower than the Vostok but that might be only in the pictures because the battery looks small in that deck. It’s a beauty either way and great to hear that it handles so well. For the brake system, two pistons will indeed heat up quite fast. The MT5 are t...

Re: EXTREMO - Scratch built 7kW billet frame scooter

Really nice to see this vision becoming reality. Thanks for sharing. This is really impressive from conception to execution ....

I wish we had a scooter design as an open source project where people could contribute as per their skill and tastes.

Re: EXTREMO - Scratch built 7kW billet frame scooter

You always have the option to design the column to include the controllers, particularly for if you are using some Nucular 12F which are relatively small and that has the added bonus of providing more cooling and letting the battery breath a bit. Am sure you considered 21700 batteries so will not go...

Re: EXTREMO - Scratch built 7kW billet frame scooter

Any suggestion how much battery and phase current I can push on this motor (continous / max) ? If this is the one that comes from the Aliexpress "FLJ Official Store" then I saw a couple guys use it on a Thunder build with the same 20s10p (40T), AntBMS 300A so that would be 150A peak they ...

Re: EXTREMO - Scratch built 7kW billet frame scooter

Why dual shocks on the rear, it might be easier and cheaper to go with a single shock design like the Bronco 11 extreme. Thie air shock I gonna use are designed for MTB that have ususally a leverage of 2:1 - 3:1 - to get a 150mm wheel stroke on such short wheelbase you have to reach 5:1 ratio that ...

Re: EXTREMO - Scratch built 7kW billet frame scooter

Seems like an awful lot of trouble and expense for a contraption that's not nearly as capable or comfortable or safe as a bike, and not nearly as lightweight or compact as a typical donut wheel scooter. That looks to me like at least two hours battery endurance, in a vehicle that would not be fun f...

Re: EXTREMO - Scratch built 7kW billet frame scooter

Its not often that we get something this exciting in the scooter category. :bigthumb: The influence of the Vostok is clearly there and I think you did a great job of simplifying some of it’s over engineered aspects. I really hope we all get to see this one come to life and am glad to support in any ...

Re: Rwd dual motor hub+inrunner chain drive 8kw capable.

Sorry no thread on any, most of this is in the "Minimotors Club Dualtron & Speedway" Facebook group and some in the "High Performance PEV" one but the mod I described in your other thread ... a thunder with a 20s10P which can push out 300A is now the standard for the higher e...

Re: Rwd dual motor hub+inrunner chain drive 8kw capable.

OK get your idea and like the determination there but not sure I see the point. I've ran stock Dualtron hubs from 40A/60v to 60A/72V some have gone to 72V/140A with only phase wire upgrade (and hall sensors) and that might be an easier way to achieve the increased output goal but have a feeling that...

Re: Rwd dual motor hub+inrunner chain drive 8kw capable.

It seems to me that you are describing is the concept of the "Quad" kit developed for the Hunter M1. In effect it consists of assembling two hub motors together to form a large rim on which they fit 13" tires. The resulting "wheel" has two motors, each power by its own contr...

Re: Nucular Electronics owner's thread (setup infos, FW updates, links etc.)

I have a pair of 6F working in a dual setup. Added hall sensors and replaced the generic middle of the run controllers and it’s a whole new thing. But it’s my first controller. I am new at this and wonder. What makes the Nucular controllers so good. Hadrware ? Software ? And how is a 12F better to s...

Re: I Don't Get It ?

I can’t say I ever did a 100 km ride but a lot of rides between 40 and 60 and it’s something that you have to try and it can’t really be explained. Over 100km I have to wonder as well but its pretty much a lifestyle in the Philippines and Korea where they are organised in “pulling teams” and go on d...

Re: Reliable and Powerful 11-13 inch 72V+ Hub Motor for High-Performance E-Scooter

- Get a cheap second hand Thunder as the base. - Throw away / sell the battery and controllers. - Build your 20s10P 40T pack which now has enaugh space to fit in the frame. You'll need to build deck riser of 2cm, to accommodate the extra height of the pack due to the 21700 cells. - Now there is no r...
