Re: Need an Nchannel Power Fet w/ VGS down to 3V

I skimmed what you want to do, with admittedly only partial comprehension. Recently I was working on figuring out how to to force an Anker Power Core 10000mah pack with QC 3.0 technology to output 6.0VDC for a particular application. What about using a Qualcomm Quick Charge 3.0 HVDCP Controller like...

Re: Free Methods LVC/HVC Parallel parts, unused

Bump.

I'm going to keep this stuff only for about another week, then it's going to e-recycling. If anyone wants these parts, act now.

Free Methods LVC/HVC Parallel parts, unused

I am clearing out some of my excess E-bike stuff. These parts were given to me by Methods when I was doing some development work for him. They were given to me, so I am giving them away. They are all new, unused, but unfinished. He grabbed them out of the manufacturing area in-process. The JST conne...

Re: MXUS 3000 Hub Motor

The Sabvoton 72V controller can handle up to 95V max, and output 150A Battery/350A Phase, with FOC. It is considerably less $ than an Adaptto system, but of course doesn't come with a BMS or read-out. It is programmable, though. That's very much a conditional statement. If that controller, and its ...

Re: MXUS 3000 Hub Motor

Well, I was playing around with it. And if you move the wheel diameter smaller, you get longer range, less speed of course. It was interesting to see that with my own eyes on the motor simulator. If you experiment with certain motor/wheel combos, you'll find a smaller wheel will give you both more ...

What do you use to remove these? Channel-spanner? :)

It would be helpful to know what the width is, so to figure dropout dimensions, rim dish etc.

Good point, The factory should of made there tyre choice a lot better It was the trend at the time. Plus, the Duro with it's thick moto duty casing is a good choice for a 120lb bike.

Re: E-S Stealth Electric Bike Owners

The Halo Contra looks so much like the Razorback, I wouldn't be surprised if it came out of the same mold. Halo USA has them on their site, but they are spendy, $50 plus ship. Chain Reaction lists them, but not in stock. The Duro 24 X 3.0 Wildlife Leopard is nearly identical. It may have a different...

It's not the weight (I'm about 190lb), but my desire for heavy duty that lead me to purchase a used Yamaha YZ85 front end for a build. However, after evaluating all the...

Re: E-S Stealth Electric Bike Owners

The largest spokes that will "fit" are the ones that are installed from the factory. The spokes in my 5403 are 9 gauge, 3.57mm in diameter. IMHO, these are way too stout for the Bomber. The spokes do not have any appreciable "spring" in them when tensioned. However, without washers on the spoke head...

I have a plastic tube on the end of my grease gun. I have this weird compulsion to stick that tube up against the VBoxx ports and start squeezing till grease is up to my arm pits. My V-Boxx is starting to act sort of funky, like the grease is getting dry. Sometimes while not pedaling, the box click...

Re: 19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tir

this is my take, the 18x1.4 rim running either a 2.75 SR 241 shinko, or an IRC TR1 is the best on the rear. I would get an 18x1.4 rim in a heartbeat (currently running a 19x1.4 pro wheel) but I spent a ton last year on stuff and while my wife hasn't said I can't get what I want she now gives me "th...

Re: E-S Stealth Electric Bike Owners

I'm figuring you're in a position to score, because the bike needs some expensive parts, and the seller probably isn't too intent on wringing every last nickle from the sale. For reference, I paid $4700USD for Bomber #77 shown in the post Allex referenced. It is a running bike, the battery is in goo...

Re: E-S Stealth Electric Bike Owners

I looked at your photos in the 5403 thread by Doc, and the motor looks nearly identical to the one on my bike. I'm not sure what the true limitation is on the controller. I believe they are set around 65A. Occasionally my CA says 70A or so for maximum current. You can turn the CA up higher, but the ...

Neil,

It's probably a 2011, maybe a 2012. If it has as little wear on it as you say, there may still be a sticker on it on the OD of the hub motor between the spokes. Mine says "5403"

Hi,
I have two unused Cromotor V3 in my inventory. I will have to replace whatever I sell later if I sell one to you. Are you willing to pay a premium to get one now? I can't make this work for any less than $650 plus shipping.

Re: E-S Stealth Electric Bike Owners

This is true efMX. Even if someone is riding a 20KW monster ebike, as long as it can be pedaled, and if the rider is pedaling and keeping speeds at 20MPH or under when the cops are looking, they will get away with it every time. No difference than riding a Hyabusa capable of 180+ mph. If you keep t...

Re: Welding battery packs in Europe

Hi schwibsi,
Is there a way to ship these full size packs by regular post (not air) from Germany to the USA? I would like to buy a pack, but the air freight is a lot of trouble and money, and I can wait a few weeks, or more if needed.
