    Best value batteries?

    I've been using hobbyking lipo batteries for the past 8+ years. I've been satisfied with their performance for the most part. My last purchase was 4x Multistar 6s 10 amp hours. That's 888 watt hours for around $320 CAD shipped, including some extra connectors and wires. That's around 32 cents...

    My stoplight sleeper Supercycle

    I recently moved to all 20 inch wheels with my HS3540 and I'm having fun. I've been racing with a guy at work on his Kawasaki Ninja for kicks and I can actually out accelerate him for about 50 to 100 meters before he takes off. I think I'm at the absolute limits of this motor and am probably...

    Quantify power savings of 3077 vs 4110

    Since I'm shopping around for another controller I'm just wondering how much power savings would I get if I went with a 3077 over a 4110 setup. I know it's probably hard to say but would 10% to 20% real world savings be realistic or is it likely to be much less? Assuming I'd be riding the same...

    Lyen 6 fet sensorless on a 407 clyte at 40 amps?

    Would a lyen 6 fet sensorless be suitable to run my crystalyte 407 at 44.4v with 40 amp bursts and maybe 20 amps or less sustained in a 24" wheel, without modification? Lyen's product description says it'll run 25 amps at less than 72v but I know these have some room to pull more than that. I...

    Help repair a blown infineon 36-72v 12 fet grin controller

    My controller was consistently overheating in a bag and began cutting out intermittently. So I opened it up and found a loose component TL783C. I also spotted a burnt resistor beside it. So I attempted to solder the transistor back on and replace the resistor with the big 5 watt one I had on...

    Anyone repair lipos with a torch?

    I just bought a benzomatic micro torch and I was hoping I'd be able to use it to repair some of my old lipo batteries. It comes with a medium sized soldering tip but it doesn't get hot enough to melt the solder on the battery. Just curious if anyone has used a torch for this purpose? I was...

    Am I missing something from my headset?

    There's only 3 parts below my headtube in order, the crown race, rubber seal and bearings. Does that sound right? The reason I ask is because when trying to install my new fork (first time for me) the rubber seal split and sticks out a bit around the edges. Most of the pictures I've been able to...

    Cheap fork upgrade

    I'm sick of riding around my seized Supercycle fork. I've been looking at swapping it out for something better, at least something that moves :lol: Hitting potholes at high speed on a rigid fork is getting old. I finally pulled the trigger last night on Rockshox XC32 coil for $200 shipped. I...

    Aerodynamics

    Just curious how many of you have put any effort into aerodynamics with your setup and what were your results? I notice when playing with the simulator there's a big difference in range at a particular speed depending on the rider position. For example to go 60kph on a mountain bike with the...

    HobbyKing Turnigy 20C lipo after 1 year, 200+ cycles

    In July 2012 I received an order of 9 packs of 6s, 5 amp hour, 20C Turnigy's, plus some cables and connectors at a cost of $580 shipped. The packs were mostly run at 24s 2p, 88.8v 10 amp hours. Current has been between 40 and 90 amps. However past few months I've been running 24s 1p, again...

    High power + Aluminum dropout + torque arm = strong enough?

    The bike in question has a rear aluminum dropout. I'm thinking about putting my HS3540 on the back with 8kw peaks with doctor bass torque arms and dp420. Does the swing arm / dropout look too feeble for that? That's pretty much the nicest bike I've got at the moment. I've got two other bikes...

    HS3540 phase wire upgrade

    I've got my HS3540 opened up. Phase wires have some knicks in them. I'm considering upgrading them, but without modifying the axle or changing the bearing, which leaves limited space for increasing the wire size. One thing is I've got a really crappy soldering iron maybe 30 watt so I don't...

    Ruined my dropouts. Want a clamping torque arm

    Does anyone offer a ready made clamping torque arm solution? I've managed to spread my rear dropouts on my cheap steel framed bike. I've also managed to round the axle a bit. I have the latest iteration of rear torque arms from ebikes.ca but they have a bit of play in them on my axle and I want...

    Riding in deep rutted snow

    We've got a pretty huge snow storm here (Toronto area) today. Snow is between 6" and 12" and deeper in some places. I tried to take my bike out this morning for my daily commute and quickly realized it wasn't going to happen. I got a Schwalbe ice spiker on the front and a snow stud on the rear...

    My rear wheel fell out today!

    I was at a stop light and I tried to pedal to cross the road and I felt a thud. I looked down and my rear wheel axle popped out the drop out! I'm lucky I wasn't riding fast when it happened. I just put my motor into a new rim this past weekend and decided to try riding without the torque arms...

    Ever pedal without power?

    I've got an HS3540 on my bike and lately I've been trying to get a bit of exercise pedalling without power for a block or two and I'm not sure if it's just me but I get excessively tired after just that short distance. Mind you I have somewhat under inflated knobby studded tires on as well. When...

    14g spokes popping out of Crystalyte rim

    I'm using a Crystalyte 26" rim and I was having the original 12g spokes breaking here and there usually giving me flat tires in the process. So I got a set of replacement spokes from ebikes.ca which are 14g with washers at the hub. I've replaced the broken 12g spokes with the new 14g spokes so...

    Regenerative brakes in the rain

    I was riding into work this morning in the rain and not even very fast maybe around 40 kph and I hit my regenerative brake and felt the tire slide and didn't feel all that safe. I have no rear brakes at the moment beyond regen. I think with winter coming and more slippery conditions I may tune...

    Regen brake wiring

    I want to hook up regen on my lyen controller. I got a wuxing brake lever with two wires, red and blue. The regen wires on the lyen controller are black and yellow. Anyone know which colours match? Is there any chance of blowing my controller or something if I wire it up backwards?

    Mixing spokes

    My rear drive wheel has 12 gauge Chinese spokes and 8 of 36 are missing due to breaking at the elbow, surprisingly I've still been able to ride in this condition. Would it be ok to replace the missing spokes with 13 gauge Sapims or will this cause problems?

    Big spark connecting lyen 18 fet for first time

    So I'm trying to hook up my 18 fet lyen controller to my hs3540. I've only connected the 3 phase wires and 5 halls temporarily. I have the thin red wire directly connected to the positive wire. When I try to hook up my battery I get a big spark like there's a short. So I tried disconnecting the...

    Delivered vs stated battery capacity

    I've been using the simulator on ebikes.ca to get an idea of how far I can go with my battery capacity at different speeds. I've finally got a cycle analyst on my bike so I can actually see how my batteries are performing in the real world and it appears that I'm getting significantly less...

    How to program Lyen 18 fet?

    I emailed Lyen and he gave me some links to profiles to use but where is the software to load the profiles? Can anyone give me some brief instruction on what to do? The profile links he gave me have EB318. Another question is what is the Rshunt value for the cycle analyst? I'm using 4110 fet...

    Help wiring lyen 18 fet controller

    I notice there is no power switch on my Lyen controller. On the back of the controller it says tap the thin red wire to the battery positive. Does that mean if I solder the thin red wire to the thicker red wire in parallel the controller will be hard wired on when connected to the battery? Any...
