    Crystalyte X5 5303 Series; & LiFePo4 Battery - Video review

    Thanks. Yes, drivers are confused to see a bike going that fast. I find to be safe, if I am riding with traffic, I ride it like a motorcycle... if I ride too close to the curb, drivers behind me want to get up beside me, whether to take a look, or whether to treat me like a bicycle ...

    Spun front axle and flew over the bars @ 25mph

    I can't see why anyone would argue with good parts and safety. I haven't argued against torque arms, just made the point that using them as a means of adding to safety, not replacing properly setting up a bike and maintaining it. No need to continue this discussion. I'm sure all who read this...

    show off your homebrew lighting......my paint can lights....

    I went with car fog lights, 55 watts halos. (Cheap at $30 from Canadian Tire). I also added low beam 35 w halo bulbs inside to allow me to toggle down for on coming cars using a regular toggle switch. I run a DC/DC convertor to deliver the power to the headlights. Also installed a proper...

    Battery Needed

    Don't dream too hard man ! It is possible, don't get too worried about all the tech talk that is out here. I bought my 5303 kit from electricrider.com and the battery from Diaw. The rest was simply assembly. I haven't had any major issues as of yet. But I guess it is kinda like shopping...

    Front suspension is it a problem?

    I ride a 5303 on front suspension forks. I read alot about the risks, but so far, I haven't had a problem. I would just recommend that they are steel... alumium snaps easier, and without warning. Rory

    Front fork failure

    I run a 5303 on a front steel suspension fork. No problems. Will report as time goes on.

    So ... just how hard can you push your hub motor?

    I ride a 5303. Can run at 2000 watts all day (35 to 45 mph), and doesn't seem to warm up much. I typically ride in stretches of up to 40 miles at a time, for around an hour or so. 25 mile rides seem to blow by in 45 mins. Seems like the Crystalyte 5000 series is the way to go, especially...

    LifePo4 charger question

    I've stopped using the BMS altogether on my battery. It was doing something similar when I tried charging my battery. Total life cycles are certainly improved with a good bms; but even if I get half of the 3000 anticipated life cycles of LiFePo4 ... 1500 is more than 5 years of charging...

    Spun front axle and flew over the bars @ 25mph

    Looking at your dropout, I can see why you and I have a difference of opinion. Please re-read my suggestions as to how to avoid going over the handle bars. There was more than just the torque wrench. Follow those steps and you will certainly reduce the risks. In nearly 35 years of extreme...

    Crystalyte 5303 Bicycle Hub Motor Chasing Cars at 70kph

    I have checked the cell groupings from time to time, but find no variation. I should know more as time goes on, since I've only pulled a couple hundred aH from the battery as of now. I do a lot of long rides - up to 120 kms in a day... so the 40 aH comes in handy. I never do less than 80 kms...

    Some advices to STORE YOUR BATTERY for the winter period

    I have a simple answer for the daily rider looking for just in time chargin. I bought a wall timer that you can program to turn on as needed. My battery fully charges in 3 to 4 hours tops. I leave my place at 8 in the morning. So, the night before, I plug my bike in and the timer doesn't...

    I feel like a 250 lbs rider instead of 200 lbs ... bikes are generally good up to 300lbs. Rory

    Did you read my post re attaching the battery? I agree not optimal, but safely attached. Did you see the video?

    Spun front axle and flew over the bars @ 25mph

    I am using steel everything.... aluminum is NEVER a good option for any parts that require fastening too. All the hype about aluminum is about weight reduction... not about increasing strength ! Steel doesn't not break in the same way as alumium. Steel also can be welded. You need to check...

    Crystalyte 5303 Bicycle Hub Motor Chasing Cars at 70kph

    If you really want, I can take the battery off the bike, open it up and film it for you. But, yes, it is dense man... I mean dense. It is air tight, and all battery, unlike the cell style batteries. It is as heavy as picking up a solid iron brick. Impressive.

    Mounting your battery, Center of Gravity.

    While lower is better, my 72volt 40aH battery is 50 lbs, and sits right above the back wheel. Don't attach with bags or anything that can move around. It's the swaying around of the weight that will make you feel unsafe. I made brackets from solid steel rods bought from home depot. I had...

    Spun front axle and flew over the bars @ 25mph

    I've worked on cars for years. The most important tool that is often not used by "home jobbers" that will solve this issue: A tork (torque) wrench. Use a proper tork wrench to tighten the nuts to the proper specification ! People mistakeningly believe that if you use all of your force to...

    Gearing or Voltage?

    I used to run 26 volts. Nothing beats more voltage. I've got a video in my signature line that will give you a good sense of what more volts can do.

    Best headlight for about $100?

    I found that the bike lighting out there just isn't satisfactory. I turned to what I know works: automotive headlights. A pair of 35 to 55 watt halogen foglights work great. I posted a video that shows the lighting set up: http://www.youtube.com/watch?v=s5sa6fC5Hig Rory
