    Grin - Outrider mini front hub quick review

    Well, it sure took me a while, but I finally got the time to put my new "bike-like-bike" together. Quick review: It’s a pretty much exactly what I wanted. The bike is almost half the weight of my fast “super commuter” which weights 100lbs with the battery. Unlike the super commuter, it feels...

    Going back to a bike-like-bike

    Hi all, haven't posted here in a while. I'm still using my powerful 100V bike that I built 4 years ago to get to work everyday. Its fun, fast and reliable, but I'm now looking for a more bike-like transport to get more exercise and ride with the kids. I'm not looking for a high end road bike...

    Broken rack, Pinch flat, broken spoke

    On 3 separate occasions, all in the last month... Everything is tightly fitted on my bike so each time its half a day of work to remove the wiring, controller, torque arms and wheel and then put it all back together and try to adjust that damn warped disk brake... The cause is obvious: lots...

    Plush Front Fork Suggestions

    I'm not too happy with my current suspension fork. Its a el-cheapo Marzocchi MZ with a 9mm axle. It doesn't look very strong and I'm always concerned that it might break while hitting a pot hole at high speeds (60-70km/h), sending me directly to the morgue. I'm ok with spending around 500$ on...

    Analysis of Commute Time vs Power Used at Various Top Speeds

    A lot of the questions I see from new e-bikers revolve around how big a motor, battery and controller they need for their commute. In an effort to help them in their decision, I recorded data on 6 different commutes using different speed settings on my 3-speed switch (I reprogrammed it a few...

    Full Face = Getting yelled at on the bike path

    I don't know what it is with full-face helmets, but I only get yelled at by other cyclist when I wear them. I make the same commute every day, most of it on the road, but some parts I have to get on the bike paths to save some time. On the bike paths, I'm pretty considerate and I take it easy...

    Ventilating the new 9c "square" covers

    After properly trashing my "old-style" 2807 rear motor: http://endless-sphere.com/forums/viewtopic.php?f=2&t=9791&start=525#p400807 I bought a replacement motor that has the new style "square covers": I'm about to open it up to do the usual phase wire upgrade and temperature probe...

    Replacing a single cell from the middle of a Lipo pack

    I was asked in the Zippy/ Flightmax / Turnigy/ Blue lipo testing (pt 2) thread to post some pics of how I replaced dead cells in some of my LiPo packs. Since this was a bit off topic, I created this thread. If you have puffed cells and are willing to try and de-puff them, see AussieJesters...

    Where to Get Clear Shrink Wrap for LiPo

    After finding a few damaged cells in my Turnigy LiPo packs (1 busted at the seam and a few more leaking/puffy), I'd like to visually inspect the cells in all my turnigy pack. I will have to re-shrink wrap the packs afterwards and was thinking it would be neat if I could do it with clear shrink...

    LiPo balance wire length vs gauge

    I charge my LiPo packs with an RC Charger. My packs are deep in my rear panniers so I have to use balance connector extensions to be able to plug into the charger. Total length from pack to charger is over 3 feet with 22 AWG. Using a celllog or battery medic, I haven't noticed any significant...

    45A Anderson contacts without TRICrimp

    So you have only a couple 45 amps Anderson contacts to install and you don't want to buy the 40$ TRICrimp tool? The 15 and 30 amps are easy enough to install with standard tools and a bit of solder, but the 45 amps connectors are different as they have flat sides instead of rounded ones. I...

    "1606" - Larger diameter 9c motor now available

    Looks like ebikes.ca is now selling a larger diameter 9c motor. Its huge (273mm) but the magnets are smaller (just 16mm) Performance is a better than the regular 9c, but at 9.95 rpm/V, the only available winding is bit fast for high voltage applications in 26" wheels. Should be good for 30mph...

    Voltage vs Current vs Heat

    Lets say I have 2 motors. One is high rpm / Volt, the other is low rpm / Volt The high RPM motor allows me to roll at 30mph at 50V, using 30 amps (1500 watts) The low RPM motor allows me to roll at 30mph at 100V, using 15 amps (1500 watts) To simplify the question, lets also assume that both...

    El Steak Super-Commuter

    Here's my finished winter project. My goal was to have something comfortable, clean, elegant and FAST. Stealthy would have been nice, but unfortunately the 9c is not very quiet. My Methods controller is software-limited at 100 Amps and I can run the motor in either 18s3p mode (75V max) or...

    Why won't this battery charge? (not e-bike related)

    My friend's brother has a landscaping business and he uses a Sokkia laser Level. The battery for this thing died and a replacement is 100$ I inspected the battery and found out it is a simple 4.8V pack made with 4 NiCd D cells. I bought some replacement cells for 4$ a pop, opened the pack and...

    First ride @7500Watts / 10000watts

    No snow or ice on the road anymore so I decided to go for my first ride with my winter project. Rear 9c Methods 100v 100A controller 18s3p Lipo (+-75volts fully charged) Holy sh1t, this thing pops wheelies like there's no tomorrow :shock: Now recharging and will reconfigure the pack to...

    iCharger 206B - charger dangerous FAILURE

    I was charging a string of 10 NiMh batteries at 2.0amps, using a 15V / 5amps powersupply when I accidently bumped the alligator clip connector on the - side of the string. (no shorts, the clips are covered in silicone) The battery got disconnected and the charger displayed "connection failure"...

    Hobbyking Shipping Issues

    I want to order 9 packs of 6S 5ah Lipo and a few other things from HobbyKing. The total weight is going to be around 10KG. I'll probably have to break the shipment in 2-3 packages. I'd like to avoid problems with br0kerage fees and the likes and was wondering if other felow Canadians had to...

    Fuses in High Amps Setups ?

    This is a continuation of the fuse discussion started in the Zippy Flightmax / Turnigy lipo testing thread. It was off-topic in that thread so I moved it here. I want to add shorts protection to a 24s Lipo setup - 100V / 75A (Cycle Analyst-limited) and I'm not sure which way to go. The...

    Nine Continents - Inside Washer

    A friend bought a 9c front motor for his Haro BMX. The BMX fork is all steel and very heady-duty. It is 100mm wide which is enough for the motor, but not for the 2 thick inside washers. Since it's short and very strong, the fork is very difficult to spread to allow the washers to fit in. The...

    New Ping 60V packs

    Looks like Ping started selling 60V packs on his site. He appears to still be using the same 2C cells though. Could be an interesting option if you have a controller that can take over 48V.

    Anybody changed the phase wires on a 9c?

    In a recent test, Justin found out that the insulation on the stock 9c phase wires would start to melt at 60A Did anybody change those wires to something larger? If so, how large were you able to fit in the axle, how difficult was it and any recommendation on the best wires to use ?

    Efficiency / throttle / ebikes.ca simulator

    I have a 2806 in a 26inch wheel and a Methods 100V/100A controller. I'm shopping for batteries and am considering a 24s Lipo setup (88volts 50amps). When I look at the ebikes.ca simulator, this setup produces great torque all the way to high speeds, but a way too high top speed and poor...

    Headway 24s1p - Best way to do it?

    I want to go with an 88v / 50amps setup for my bike. 10ah is enough, but I need to be able to carry the charger(s) on the bike. Headway cells are very tempting but I'm not sure which way to go with all the packs, BMS and charger possibilities. I came up with the 3 ideas listed below, can I get...

    How many watts can you safely feed a 9c?

    Just ordered a big kahuna 100v / 100a controller from Methods. Got all the bells and whistles like regen, 3-speed throttle and cruise control. Way overkill, but it's going to be the last controller I'll need in a long time ;) I'm now looking at the different possibilities for my battery setup...
