Re: Stealth FUTR owners builds and pics

Mail call!! https://preview.ibb.co/jZwszb/20171208_182830.jpg NIce battery. plenty of room for running the wires. Is that an Alex special? It's a double-decker, PITA to make them! Just make sure to use dampening material at the bottom of the frame for battery protection. closed cell foam is the best.

Re: Sur-Ron - New Mid drive Bike from China

Controller spec: 80A DC 60V*80=4800W peak output. 60v is 176 cells 32ah 1900wh (Panasonic PF) Should be 16s11p and would make it to 31,9Ah If we count that 1s is 3.6V then 16s*3.6=57.6V*80A=4608W 11P pack with PF cells is good for maximum of 110A so the current at 80A is fair although the pack can s...

Re: Homemade Battery Packs

Got it, I looked at that but somewhere in this thread said that was not necessary that's why I doubled up the other parallel connectors. I shall go back and do the other side of that series bridge and make that additional connection. Thank you for clarifying with pre-tinned strip it makes an easy t...

Re: Sur-Ron Light Bee USA group buy

I find that the problem is that the stuff is too cheap nowadays.
When you need to pay 7 bucks to sharpen a knife at a local shop but instead choose to buy a brand new (that was imported from China) for less, there is some seriuos fuckup in our society.

Re: Sur-Ron Light Bee USA group buy

^^This I mean it was not that long ago we bought Carbon ebike frames from Canada at 2000USD. People are still buying bulky frames from Stealth at 1500USD. And here you have a fully working bike for about 3 grand. Its is frigging cheap. And come on, the sur-ron target audience is those thousands or r...

Re: Sur-Ron Light Bee USA group buy

2000 dineros is dirt cheap for a bike like this even when you know you have to spend another grand.

Merlin, the contact person at sur-ron is not that tech-savvy, he types for instant that the current of the controller is 80Ah instead of 80A

Re: Definitive Tests on the Heating and Cooling of Hub Motor

Meanwhile in Russia, they take another way to cool down the motors. It seems that ferrofluid is not enough for them so they actually use Active cooling and it is far more complex one.

Re: Sur-Ron Light Bee USA group buy

I think the purpose of this bike is to be small?
Its like a miniature version of a motorcross bike but bigger than a pit bike.
If you want a full size then go for a KTM freeride or similar.

Re: EU - MAC 12T motors in 24" rims

There is no such thing as 36/48V

You can use them on 24V or even 100V
Higher voltage gives you higher speed.

EU - MAC 12T motors in 24" rims

Hi guys I have 4 identical motors that was installed on NYX bikes. These motors only run for about 30km so consider them as brand new. They have been standing unused for over a year in a shed so you may see some rust on nipples on the inside of the rim. This is the latest version of MAC with redesig...

Re: E-S Stealth Electric Bike Owners

P7 in the field. I just finished up lacing a 26MTB wheel to the motor to pick up a little mechanical advantage over the 27.5. It works great. At first, I thought the P7 may be my new favorite Stealth bike because It was new to me. Not the case though. Its my favorite Stealth Bike. It wont touch the...
