Wow Rix thats a heavily modified P7 !! My bike is serial number 41. I remember when i ordered it that they said mine came with the latest upgraded battery pack. I just looked at the motor. Cant see a brand name on it but it does have a part number (M20171-0036) . Hope that helps mate. Im afraid im a real novice on the ebike scene, so would really appreciate advice on what motor etc to buy to get me up these hills ! I specialise in machining, tig welding and fabrication but ive always stayed out of the electronics game. Cheers mate.
I have to P7, the first P7 has a serial number of 000, and the P7 I have in the picture is 096. Anyway, lets see what you go, can you take a picture of your hubmotor on your bike and post it, I can tell by looking at it if you have a MAC or Bafang.

Can anyone help me with gears, i have the mk1 the knock off and it looks like i can install a cassette at the back but not at the chain ting as I cant see how I can attach a front derailuer. can anyone advise me please

Ciao Davide, can you also take a pick of your motor, some motors come with a cassette hub installed, and some are only threaded to accept a free wheel. You will not be able to mount a front derailleur without some modifications to the frame...probably. I never considered doing that but dont think its possible on the PS due to the fact the BB and Swing arm pivot are the same axis.

Hey Rix thanks for the assistance. Hopefully my pics attach ok. My first go on here. I am thinking its a MAC motor going by quick internet search. Do you know the specs of the factory motor vs a 12 turn MAC motor ? I am hoping all going well that i can buy a 12 turn MAC and lace it into the spare 27.5" rim i have and it will work with the factory controller etc ? Would you also know the plug on the motor side that i will need to purchase so that it will plug into the Stealth plug on the swingarm. Oh and i guess do i purchase a motor direct from MAC in china ? I am in Australia but so far i haven't found an Australian seller of these. Apologies for the basic questions . Ive always been into motorbikes and quadbikes. This ebike thing is all very new to me ( and great fun to ride)

You have the Mac motor. The Stealth Spec'd Mac motor is a 9T wind. I don't know if you can buy a 12T set up to directly plug into the stock controller, you may have to set that up your self. That said, you wont notice much of an increase in acceleration if you use Stealth's stock controller, they have it programmed to not start off quick, but to add power gradually, thats why your bike is faster at accelerating above 5-10 km/H than it is from dead stop. Getting a 12T in a 27.5 rim is no problem though.

I just happen to have a new 12T for sale
It is laced but I can unlace it and you would need to change the connectors, or maybe I can help you with that.

Thanks Rix. Oh that's interesting info. I did message Stealth about the acceleration curve programming. They said it was factory set and couldn't be changed. The factory setting makes it quite challenging to get started on a steep road . Sounds like i would be better off using a 26" rim like i already have on the rear, seeing that Stealth already have a 9t wind and i would like to maximise torque whilst still having 26" or 27.5" rims with a 12t wind. That said then which type controller am i best to buy to suit ? Its all factory standard at present with stock big battery and controller etc. Thankyou for your help mate. Much appreciated.

The program power curve may be set at the factory, I am guessing Stealth specified the ramp up mode though. I would hit up Allex and get that 12T he has. If you go with a new controller, then you will need to go with a Cycle Analyst because the DC1 would have to be reflashed by Stealth, and I don't think thats something they do for folks who want to modify their bikes. I bet Allex could get you set up to plug-n-ride with our stock unit, and it will accelerate noticeably quicker, just not from dead stop. And your plan to use a 26MTB wheel will also help.

Cool thanks for that Rix. Allex is your motor still the latest version available from MAC of this type motor? As you say it would be interesting to see if it can be compatible with the stock controller, but if it needs changing then thats fine. I bought the bike mostly to help me get up the steep mountain roads at home, but unfortunately that is its one weakness in stock form...

referring to Pete de Vries's post:
so... Allex's motor is in a 24 inch wheel... Rix's P7 has a 24 inch wheel, which seems to work well - why wouldn't a mac 12T, in a 24 inch wheel, if needs be with a new controller and CA3, be the answer? What battery has the P7 got, i.e. how many amps could be drawn out?

Hi there i am hoping to run a 26" or 27.5" wheel as the Stealth P7 comes factory with 27.5" rims. If i need to i could swap down to 24" but to be honest id prefer not to go below 26" as it keeps it looking quite "push bike ish " in the local park areas etc. Ultimately it would be great if i could just fit a 12t MAC with everything else stock on say a 26" rim , but im open to do whats necessary as i still have to resort to pushing my bike up the steeper roads as even with power and pedals its still not enough oomph in stock form ! And i am getting ever closer to needing new knees so i would like to look after whats left of them lol.

ok, I will wait for Rix to comment - or a mac 12t in the front as well, with an additional controller?

Yah, the 24MTB tires are so sweet on the P7s. My dad liked mine so much he went to a 24 wheel setup on my other, or I should say his now P7. My uncle is running a 24 rear 26 front on his Beta and loves the 24 on the rear. Hes got a Mac10 running the same controller and 12s, so top speeds are about the same as the 12T and the 13s. The P7 battery comes with a 40amp BMS, so it can handle that much. Stealth is very tight lipped about the cells in the pack, but I do know we have 18650 cells, just don't know which ones.

Here are some pics of my P7s and Beta. The top pic is of P7 ser#000 with the stock wheel up front and a 26MTB wheel on the rear before we went to 24s front and rear. The middle bike in the top pic is of my Beta with a Mac10 24MTB rear and 26MTB front with 2.6" wide tires. Bottom pic is a close up of the Beta.

Thanks Rix for the info. Wow you have a nice collection of Stealth products !! Yes im thinking i will try for a 12t MAC in a 26" wheel, but if it still isnt quite enough then i will go down to a 24" wheel. I will leave my 9t factory MAC and 26" wheel as a complete unit as its great for the longer flatter rides, just not suited to long or steep uphill sections. One question for today, is my MAC motor able to have a cooling fluid added ? Ive read a little so far that some motor types can have ATF or ? Castor oil ? Added will help with heat transfer. Sounds like a good idea at least. Thanks for the advice, much appreciated.

David Pearce and Kepler have both experimented with oil cooling these geared hub motors with success, at the price of being messy and hard to keep the fluid inside of the hub motor. That said, its not something you will have to worry about if you are going to run a 12T with the stock controller. Because the controller is inside of the frame, it will get hot and go into thermo roll back long before you get the Mac 12 hot enough to do any damage.

who is using 26” x 4”
i have 177mm dropout and ive read that it is 26” with tyre and the rim is smaller, of thats the case i can get the wheel and tyre in with a few mm to spare especially sinve as it narrows the tyre should round off too. Problem is ive also read 26” comes up as 29” something with tyre!
please advise
