    Electric Harley.

    Looks cool, not bad as a prototype (not considering the useless range), fair play to Harley - last company i would have expected this from. http://www.pistonheads.com/features/ph-ph2/harley-davidson-project-livewire-ph2-review/32181

    Gradual, smooth, progressive throttle? HOW??

    Wow, this sounds ace Tek. I have already have a three speed switch, but the progressive power roll on advanced modulation stuff sounds like the business. Would be interested to learn a bit more about this, will certainly pay the grin cyclery a visit though.

    Gradual, smooth, progressive throttle? HOW??

    Hey guys, I've just got my MAC 12T running on 40a and its a bit fruity, I have wheelied off the back twice today and need a little more throttle modulation....and maybe some more skill as well. Did anyone find a solution to this issue? The standard Mac throttle I have is pretty much on / off...

    Can I use my Crystalyte controller with a MAC motor?

    I'm sure this has been asked before but I'm searching to no avail..... Crystalyte 72Volt 45A digital sensorless controller CT-S-72V45A-R for brushless HS3540. I want to buy a MAC 10T and use this controller if possible. Can anyone give me a firm yes, and if so some wiring guidance? Much...

    Best smallish high torque motor

    Guys this is all good, thanks for the ideas. Ideally id like to go with a mid mount as this will be a proper trail bike and i want to keep the unsprung weight down but i've not seen a decent retro fit kit yet. Hydro - what are the Mini monsters like? I considered buying a Lyen controller for...

    Best smallish high torque motor

    Hi guys, So, collective wisdom, what is the best smallish motor for a high torque setup? Im not too worried about top end (25 would be cool) but i want power wheelies. Clearly if i buy a gargantuan DD hub and throw 100's of amps at it then I will have a high torque beast, but i want to try...

    Specialized Big Hit FSR with midmount

    Just stumbled across this thread and I'm blown away. I didn't have the skills or the balls to consider chopping my big hit, hats off to you for doing a proper job. Did you heat treat the frame after welding or just go as is? Massive respect for a professional build, you are a very talented...

    Another flying car

    That is pretty decent, and reasonably usable as well as long as you have the space to take off, i want! I also want one of these little beauties.... http://martinjetpack.com :D

    Off road trail Ebike + home-to-work ebike: need some help

    This is what you want: http://endless-sphere.com/forums/viewtopic.php?f=6&t=32754 unless you are riding in the desert i wouldn't worry about overheating, I have hacked the big hit all over my local trails and its never had a problem, in fact its usually me that overheats not the motor! I'd...

    Anyone know Solid Works?

    Nice first foray into solid modelling! Get some assemblies done and have a go at rendering some stuff - BLING! I use Solid Edge for my job - design bits for planes, but i've always wanted to have a go at Works, where did you find a copy if you don't mind me asking? :-)

    Custom Full Suspension Flatbar Road bike build

    That is a quality build.....hats off to you, very nice indeed! I'm thinking of doing something similar, maybe based on a full sus 29er or a full sus road bike (if they make them?) Perhaps a Moulton would be sweet....anyone done a Moulton conversion yet? I love reading about quality builds like...

    "PVC pipe" lipo battery case build

    I used the same stuff on my Big Hit - Wickes sell it by the metre here in the UK. :D

    battery range comparison

    Hi all, Id be inclined to agree with John here, not that i know anything about this, but just looking at the numbers Lipo gives you 1V usable range (4.2full to 3.2empty) and A123 gives you nearly double (3.8V to 2.0V = 1.8V) so i would assume you would get nearly double the range because you...

    Specialized Big Hit + Crystalyte HS = :-)

    Hey all, Garrick, Yes i did want to put the controller in the frame, but its just a bit too big, grrrr. I was gonna mount it on the triple crown on the front forks....seemed a bit crap though. I bought the kit ready to go from Crystalyte. The motor was in the hub, all i did was wack a tyre...

    Specialized Big Hit + Crystalyte HS = :-)

    A few more piccies i've taken so far. So far she is holding up reasonably well, a few niggles needed sorting, nothing horrendous though. The on / off switch on the controller is really cheap and nasty, add to that the fact that i've put it in probably the worst place for...

    Big ballache, over discharged my battery, is there any hope?

    Sweet, i was worrying over nothing, gave em a charge and they've come back up fine; bonza! On another note though i've noticed my JP EN.ER.G Pro charger isn't great at balancing the packs. I've balanced them twice and the best it can do is 4.171 on one cell whilst the others are all around the...

    Big ballache, over discharged my battery, is there any hope?

    Cheers Itchy, will give em a brief charge tonight and hope for the best. Fingers crossed it's not as bad as i'd thought.

    Massive respect, 55 on something that short must be pretty crazy. :D Hoon safely!

    Big ballache, over discharged my battery, is there any hope?

    Hi all, Been loving the HS Big hit for the last month or so. Been hooning to and from work, hooning over the heath, round the lanes and over the fields.....had 54 out of her down a big hill the other day. :D i've also been a bit slack with balancing my cells and after yesterdays ride the...

    Specialized Big Hit + Crystalyte HS = :-)

    Nicobie, Afraid I dont know who Kenny is mate. The documentation i have refers to it as an 'APM Display'. You can select the controller amp limit from anything from 0 to 50amps, hit enter and thats what it will draw - i've tested it and it does work. The display gives you a relatime current...

    Specialized Big Hit + Crystalyte HS = :-)

    Knoxie - Yes, sunny Bournemouth. I've just had a look at your I drive thread - very nice, come down with the GT when its done and we'll go for a hoon. I like the battery box by the way - from Wickes perchance? DimGr - Crystalyte Europe, they were fairly helpful, a chap called Thijs seems to...
