Re: Stealth FUTR owners builds and pics

Hey Lash, Before you go spend big $$$ trying to solve your chain drop issues, if you have a 3D printer, I suggest having a go modding my chain guide to suit your needs. https://www.thingiverse.com/thing:3154020 https://cdn.thingiverse.com/renders/64/f1/43/33/28/d3ead9ec5695ac284fa8494edeb7d9da_previ...

Re: E-S Stealth Electric Bike Owners

I just got a brain storm. Why am I stressing about the width of the battery? I wouldn't care if it was 1 1/2" wider then the frame, if it fit the other dimensions. I could easily fabricate some kind of spacer to take up the gap. That should increase the possibility's I would think. Yup! I did this ...

Re: E-S Stealth Electric Bike Owners

36cm ×15.5 ×11.5 is the size to fit in the bomber? Em3ev said they could fit 21 s 7p with BMS. I would not go as low as 7P with any cell on the Bomber or Fighter. Even with a cell 30Q cell capable of 20A+ you are then limited to ~20AH and will be stressing the cells with every 5KW launch. That batt...

Re: E-S Stealth Electric Bike Owners

That must be for a Fighter? I don't think so. I squeezed the maximum you can fit in a Fighter...you cannot fit 2 vertically stacked layers of cells. I had to lay the top cells down horizontal to fit the 2.5Kwh pack I have in my Fighter: DSC_4287.JPG No Battery Murdering System on this though....I h...

Hi have 500 Sanyo GA cells on the way to Australia. I'm hoping they arrive before Christmas given the delays seen with my two previous orders.

Re: Stealth FUTR owners builds and pics

Has anyone else done anything like this yet for their Alpha? I know Lash made a similar pack a while back, but can't recall if it was 14p like this. Hey CD, my pack was 20s10p the cells were nested together but only 5 wide i think from memory. I like simple packs so you can build fast. 14s14p is 19...

Re: LMX 64 : Freeride Ebike with dual drive and torque sensor

Still no mention of top speed....we all seem to want to know....as long as it's not less than 50kph I think most will be happy.

Also, is it possible to use a belt instead of chain? That would make it quieter.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I'm really surprised that you can get rid of all that heat. The 48v graph from leafmotor shows that 3.5kw is 75% efficient, so you've got a ton of heat to shed. OK, no way you are running that power at 48v.. instead you have.. 52.. 60.. 72v? At best you're seeing 80% efficiency. Which is still arou...

The 1500w has a shit ton of potential if you add hub sinks and ferrofluid.

Or better yet, forced air cooling. :)

VERY interested in the frame kit!!! Selling my Stealth Alpha and might also sell my Fighter if I can get this. I like long range...something the stock version of this bike is lacking. I would solve this by either trying to make the big haillon case fit or having 2 (maybe 3) of the standard size pack...

Hi Guy's, If anyone was on the fence about this, you might wanna make a move as I've just listed the bike on Gumtree. I expect it will generate some keen interest and really don't think it will last long. To wet your appetite, here's some more photos: P1070780.JPG P1070779.JPG P1070789.JPG P1070796....

It's over a year since I last changed a tyre on this bike and I've put over 4000km on it since then so now well overdue for new tyres. I'm sticking with the same Maxxis M-Tread 20 x 2.1 tyres in the rear and Schwalbe Big Apple 16 x 2.0 in the front. I've not had any issues with traction or punctures...

Re: Stealth FUTR owners builds and pics

Nice work CD. Are you printing with ABS ? It'll be interesting to see how it holds up - it looks like that narrow section where it bolts to the mount is a weak spot, though I guess if it's solid it'd be strong enough. I use a topeak front mudguard cable tied directly to the shock mount and find it'...
