    How much over-wattage can one usually get away with putting into geared hubs?

    I bought a job lot of puma geared motors in 2007, nominally 350/500w. Usually run them at 54V/60A, so around 3000W but have had them up to 6000w. I maximize the size of the phase wires by using stripped 10awg wires and running them in heat shrink through the axle. Power loss/heat generated is...

    Lyen 18 FET 4115 Mark II Controller- blown Hall circuit or something else?

    Thanks, I’ll check these. Btw I’ve emailed Edward Lyen to see if I can get another of his controllers, but haven’t received a response, and I note he hasn’t posted since September- do you know if he’s still making them? Could you recommend an alternative for up to 120v, 60A, ideally with...

    How to Restrict?

    Discreet magnetic switch that triggers granny mode unless a magnet is present. Double a piece of tape over the magnet, discreely pull tape when required. Ideally, mount the switch inside the controller case. This is also a good technique for a kill switch that activates the brake circuit when no...

    Lyen 18 FET 4115 Mark II Controller- blown Hall circuit or something else?

    Thanks... how do I verify that it's not reading the halls? My motor/ controller tester normally shows rotating leds but nothing lit up when I tested the controller... can the MCU be replaced? It's a great controller and hard to get another...

    Lyen 18 FET 4115 Mark II Controller- blown Hall circuit or something else?

    Blown something in my Lyen Infineon controller. Initial problem was that a combination of heat and mechanical damage caused a phase wire to short to one of the hall sensor wires, frying all the hall sensors in the motor. Rewired the motor and replaced the hall sensors, and it ran fine, but a...

    Infineon Controller Settings Corner

    Hello all, returning to the forum after a long absence building a house and suchlike :) I've just acquired a couple of Lyen 124110's and am wondering what are the default settings it comes with? I'd like to boost the current limit using the software but I'm not sure what it's set at at the...

    New Puma motor with old type Crystallite 35A is slow. Why?

    Haven't posted for a long time so I thought I do a quick update... I ended up building a second KMX using the same spec, except I've now switched to lovely ping batteries. Spec is now 3x24V 10Ah Ping v2.5 batteries, Team hybrid puma with steel gears, 40A Crystallite analogue controller...

    Crystallite V1 always on full throttle

    Thanks Rick... I really appreaciated your detailed and fast answer! It's very possible there was an incorrectly wired throttle, I was trying to find a working throttle out of a box of dodgy ones. I don't have a spare 35A V1 controller, but would I be able to find replacement bits on a...

    Crystallite V1 always on full throttle

    Got a crystallite version 1 controller, 72V, 12 4310 fets. Whenever it's switched on, it runs the motor (406) at full throttle. Happens even if throttle is unplugged inside the controller. Anyone got any idea why? thanks

    Version 2 Crystalyte Controller information

    Hmmm... trying to reverse my V2 but grounding the suggested DSP pad has no effect. Any suggestions?

    New Puma motor with old type Crystallite 35A is slow. Why?

    groovy! hows does one get a kelly controller? I understand about backing off the throttle, I was getting 65kmh before I backed off... Later I hit a tree root and rolled it. (ouch). Then I shredded my nylon gears!

    40mph safety

    I had a nasty stack on my 84V 35A KMX Puma the other day- hit a tree root lump in an otherwise empty car park at around 40kmh, rolled several times. Lots of grazes and bruises but nothing permanent. If you're getting over 40kmh you need tough gloves and a really good bike helmet at least. Over...

    Pumas to Have Metal Gears on High Power

    I got 2 days of mind boggling performance out of my new Puma at 84V / 35A (in a KMX) before hearing a strange noise and sudden cessation of wheelspin while going up some really steep gravel. I'm assuming my nylon gears are shredded. I will now go and order some steel ones!

    not slow any more... 35mph, and still 28V to add... woohoo!

    New Puma motor with old type Crystallite 35A is slow. Why?

    I've just fitted one of the new Team Hybrid Puma motors to my KMX. I'm using an old type crystallite 35A controller with 12 x 4110 FETs, and 56V LiPOs Performance is quite sluggish, Vmax around 30kmh, poor accelleration. Motor phase wires are quite hot after 5 mins ride. The controller had 4 x...

    rim and spoke measurement guide

    I got this ebook to get me started building wheels for my menagerie of ebikes/kmx's. It's very good! It will explain everything you need to know. Haven't had any wheel or spoke probs since I read it. There's also a spoke length calculator. http://www.wheelpro.co.uk/wheelbuilding/book.php...

    Crystalyte 406 Rear Hub Motor With Disk Brake

    Some brake ideas- A mate of mine succeeded in putting an 8" disk on the rear of his KMX 408- Clearances are very tight. The disk is bolted directly to the side cover (see pic) You can also use a Magura Hydraulic Rim brake- These are easy to fit to most bikes and work almost as well as a disk...

    KMX Motor Selection Questions.

    On the subject of rear brakes, I'm in the process of fitting a set of Magura Hydraulic Rim brakes to the rear of my KMX so I can do handbrakies. I'm running a 406 which you can't really add a disk to. The 406 does about 63kmh with 86V and tyres at hookworm tyres at 90psi. I've already upgraded...

    Pictures of a new geared hub motor in the pipeline.

    This motor is almost identical to my nylon gear pumas. What sort of freewheel does it have? The puma one is a weak point. I concur with the need to fit steel gears for high power applications. After my freewheel failures, I converted my two pumas to fixed drive, which worked fine for a while...
