Re: MARRS Electric Cruiser

I currently use 3" Kenda Flames on my cruiser, good tires but very thin side walls, the hookworm is much better with its kevlar sidewall but they are only 2.5" wide.

Duro Beachbums are supposed to be good but hard to find in the UK. I'm thinking motorbike tire is the way to go .

They are motorbike tires, and motorbike rims, but can't find any details of what particular model. I'm after some big fat tires to go on a 24" DH rim.

I replaced the main power cable with one I confirmed to work on a different device. Wires from socket in charger to PCB look intact

Re: BMS Battery Alloy Shell Charger Problems

the battery was not plugged in, my process remained the same as ever. turn mains socket on at the plug, turn toggle switch on back of charger, wait until LCD display shows correct voltage (guess thats caps charging up) That's when i usually plug in the battery, but before i reached that stage the re...

Re: BMS Battery Alloy Shell Charger Problems

Here's my story. 1200W charger, 49.8V out the factory for a 4.15V per cell end voltage with 12s of Lipo. Worked great for 6 months charging 12s2p pack up every day. Left it unused for a week, turned it on to charge again and POP tripped out the ring main in my house Now it won't turn on at all. Fuse...

BMS battery charger kicked the bucket

Heres the deal, been using my BMS battery 1200W charger for about 4/5 months now everyday with no issues to charge my LiPo pack. I haven't balanced the pack in at least 3 months as no cells were off by more than 0.02V (checked every charge) Due to work commitments I hadn't ridden in over a week, lef...

Re: Mac10t verses HS3540 on 1600 watts

Thx for this review! Those photos look very similar to stuff I ride here locally. I've always just tried throwing gobs of power into DDs, but I'm beginning to see the geared light. My current controller maxes out at 2.5kw anyway so I think a 12T MAC @ 75v is my ticket to e-paradise. Gotta fry my ne...

and what voltage do you run your 5306 at? I'm having a bit of a love/hate affair with my 5306, I love its unmatched torque but it lacks top end speed (obviously) and it's a bit of a boat anchor which is noticeable on tight single track and when it's in the air

Re: Mac10t verses HS3540 on 1600 watts

very good comparison and it mirrors what i have found over the last 6 years running both motors, 1600w is the happy power level for these geared motors, dont be tempted to push it further unless you like buying new clutches and gears. Some of the posters are slightly missing the point in that you c...

Re: Mac10t verses HS3540 on 1600 watts

Another thing worth noting, the loudness of the Mac 10T differs hugely depending on the frame I have a 10T and on my rigid alloy frame beach cruiser it's pretty dam loud with the gear noise reverberating through the frame, people hear it coming, the same motor and wheel on the full suspension alloy ...

Re: Magura Hydraulic V brakes?

I'm interested in their ability to not suck in terms of one pad dragging or working fine for the first 10 miles and then being crap after that. My bike doesn't go over 20mph so high speed isn't really a problem, the back rim is an alexrims DM24 but the front is the standard Schwinn, if it's anything...

Re: Magura Hydraulic V brakes?

I agree, thanks everyone for the advice so far, I was looking at the Monark II springer fork which supports disc mount but it doesn't support a front fender, which I really need as it's for daily commuting on wet roads. It is indeed a 1 and 1/8th headset and I have no problem with upgrading to disc ...

Magura Hydraulic V brakes?

I've been looking at some Magura Hydraulic brakes on fleabay as a potential replacement for the piss poor cable V brakes on my beach cruiser. Even after a thorough clean after a few weeks one pad will drag on the rim and wear itself down fast. I go through an alarming amount of brake pads riding eve...

Re: Cyclone controller 48V 36V compatible?

Lucky the guy wasn't using LiPo or he probably wouldn't have a house / garage anymore. Is the pack beyond saving now? I could just use a tired 36V Ping for a secondary pottering around bike.

Re: Cyclone controller 48V 36V compatible?

leaving it on shouldn't kill the battery? you tried reading the cell voltages bypassing the BMS of the pack? perhaps try trickling the cells back to life? Might be able to raise it from the grave. Cell_man makes good packs. You need to get yourself someline like a Lyen Mini-Monster 6 or 9 fet contro...

blast from the past lol Sorry to bring up this old topic, but I was wondering if I could run the 36v Cyclone controller on 48v if the LVC is in the throttle and not the controller? In theory, it depends, are you using the headline controller? I'm not sure if you can because certain components will ...

Re: Cyclone controller 48V 36V compatible?

The LVC is the low voltage cutoff, the Hua Tong controller is pre-set for 72V and has a hard wired low voltage cut off of around 55V (I think) which is the lowest point an SLA battery has any charge left. Running a 36V pack you are below the LVC threshold of the controller. The LED battery meter on ...

Re: replacing dead hall in a MAC

so the controller is reading the voltage value on the positive 5V feed, thats how it senses position? by a dip in the voltage on the 5V feed, not a dip in the voltage on the hall wires themselves......

Re: replacing dead hall in a MAC

did you read what i said? there is no voltage return. the hall sensor sinks current. the voltage drop across the resistor when current flows through it drops the voltage and changes the logic state for the controller to detect. not sure why you could not just test it before you got to this point. j...

Re: replacing dead hall in a MAC

i explained already: "what you wanna see is when the hall sensor turns on and it draws current out of the controller through the resistor, which causes the voltage to drop at the plug. so the voltage toggles on and off as the hall sensors switch on and off as the magnets in the hub pass by." So how...

Re: replacing dead hall in a MAC

Thanks, I'll probably do the test with the side of the motor off so I can manually rotate the magnet ring, rotating the wheel backwards makes the magnet ring rotate 5 times quick which will make diagnosing it a bit more tricky I guess. Instead of wiring up the controller can I just wire up 3 AA batt...
