Green Machine said:Yep i am getting the same clunking at 40kmh....its extremely annoying problem.
I am running a lyen 12 fet extreme controller with a 50 amp continuous output battery.
At 72 volts i notice the problem is very pronounced....it feels like something is about to break within the motor...at 48 volts it is not so bad.
Am i doing damage to the motor at all when i hear this clunking?
SO the only way to get around this is change to hall sensors? I bought a motor without sensors...
By the way if i give too much throttle at start up i will get the motor to freeze up at start up....but in most situations as others have stated i do not get the problem at start up.

Regen with the lyen controller is a real nicety...ideally you should use it in addition to rear disk brake...but i was not able to adapt my hydraulic disc brakes so had to use Avid bb mechanical disk brakes which hooked up fine. There are clearance issues working the disc brake around that giant hub motor.
You need special brake lever that hooks right to the controller...the brake handle also has a lead going to the disk brake....when you first touch the brake the regen cuts in...its either on or off...no variable...its enough to where you feel it and it slows the bike. It is really really nice on long downhills where you just ride with the regen on to keep your speed down and pour juice into your battery....if you need a fast emergency stop the regen isnt very effective...thats why i use both regen and disc brake on the rear. SImply when i first press on the handle the regen kicks in...go in a little more on the brake lever and you start to feel the disc brake to kick in...i highly recommend this type of set up...i can still lock the rear wheel with the disc brake at speed...fun for scaring pedestrians out of my way.
The level of regen is set in the controller...but comes with maximum regen activated from the factory which is ideal for me....it slows the bike like a boat if that makes sense...you just barely feel it kicking in. It slows the bike gradually.
Its a nice efficient slow down that does not heat up your rotors and throws juice into your battery...someone should be charging $250 for just this feature. :wink: Yeah i really think its worth 250 given what hydraulic disc brakes cost. Variable regen would be tits...something we will probably see in a few years...it would be ideal if we could go without the disc brake on the rear.
Also i cant stress enough...if your going to run a lot of amps through this stuff..please spend the money and have a top of the line hydraulic brake in front. Dont skimp on brakes...and really try to get a rear disc brake working..dont cut corners on braking. Personally i am running a carbon elixer avid brake up front and swear up and down by it....however....damn brake cost me more than the crystalite motor.Thanks china!

Heh you've never used regen before have you ? What you're describing is standard regen that most controllers have, even some $20 ones! It's not some unique or special feature of this controller. It's definitely handy for casually slowing down or holding you back on steep hills but it's no substitute for even basic rear v brakes. Variable and stronger regen however is something we're all looking forward to.Green Machine said:Its a nice efficient slow down that does not heat up your rotors and throws juice into your battery...someone should be charging $250 for just this feature. :wink: Yeah i really think its worth 250 given what hydraulic disc brakes cost

curious said:How does HT/HS series compare to 9c and x5 in terms of rolling resistance ? Closer to 9c or x5 ?
Bazaki said:There is less resistance than with an X5 hub, and another good thing is there is no resonance that I have felt with the HS and HT version, the X5 has a resonance at 8 km/h and arround 20km/h. It can be annoying if you bike a steep hill at low speeds.

The resonance speed depend not on the motor itself but on the wheel diameter you installed on it..
Yhe HS and HT should have more resonance because of the cogging they have straight magnetic tooth compare to the X5 that have angled magnetic tooth to smooth the cogging.

I finally got my ht35 mounted and tried it out yesterday. It's so loud it's embarrassing! it grumbles and howls from 0 to 10 mph then its ok until about 20 mph but quiet faster than 23 mph. My bmc v2 was MUCH quieter. I'm pretty sure It's wired right as it's pulling the right amount of amps and runs real strong. Fastest I've had it was 35 mph but it would have gone alot faster if the damn phase wires hadn't shorted out after only 1.5 miles.![]()

Screw it, Maybe I'll take it apart next week. With the luck I've had lately, I probably cooked the new controller too :x
Thud said:Nick,
would you like Luke & Myself to give it some "special attention"?will defo be lighter!
OT: Are these mostly getting Imported as sensorless motors?
Something definitely sounds wrong there. Was it the 13ga wires you melted ? I've put a solid 5kw through stock 9C phase wires which are alot smaller and not melted them so it sounds like you had the controller wired wrong somehow.nicobie said:I finally got my ht35 mounted and tried it out yesterday.
