    Cute Q100 lightweight builds slow mtb, fast road

    Thanks all. I have it working with a hall sensor controller (I think from DIYmoped.com) which is a 48v, 250w controller (I need a small size and don't care about the power). I get a little groan from the motor if a heavy throttle is applied at a slow speed but then it does fine once you're...

    Cute Q100 lightweight builds slow mtb, fast road

    It must be spring as I'm working on a new build... and I can't seem to get all of the pieces working. Sigh... I have a Q100C CST and I am trying to use an existing, small 48v battery. I had a spare 48v controller from BMS Battery, the S09P-BL. See below...

    Is there an advantage to the Grin Technologies LiGo block(s) (assuming 3 to give you 294 Ah) compare to the Luna 52v Mighty Mini Cube? Note- I realize that the LiGo blocks can be transported by plane and the Luna battery is 52v vs. 36v for LiGo (and that the Luna @52v will have a higher rpm in...

    Great info. Can you post a link to the carbon bars from Amazon?

    Cute Q100 lightweight builds slow mtb, fast road

    ScooterMan101, Sounds like bicycle heaven! I'm convinced that there is a market and need for a relatively light road bike with assist from a light weight motor for many. ( I wish my legs could push what they could 20 years ago!). With a little electric assist, you can push past weaker knees...

    Cute Q100 lightweight builds slow mtb, fast road

    I'm happy with my current setup but the controller is *big*, compared to the battery and my need for power. Are there any rated for 48v that are as small as the S06S out there? I tried another one with a different display but it had trouble with the Q100, basically turned on and off as I...

    Cute Q100 lightweight builds slow mtb, fast road

    Jumping in here... but d8veh, Motomech and others have much more experience with this than I do. I've added a Q100CST on my road bike. I used a small 14S 52v (nominally) mini-cube from Luna Cycle. My setup is PAS only and I've been through a variety of controllers to get things just right...

    Cute Q100 lightweight builds slow mtb, fast road

    ScooterMan101, Thanks. And a great suggestion. I ordered the S-LCD 3 display to replace my existing LCD display. It's great to be able to monitor the motor temps and watts. I took the bike out today and it performed flawlessly wit the larger controller but I was careful to keep the assist...

    Motomech- Although I did order a BMS B. display, it was the same display that I received from greenbikekit (gbk) and the gbk works with BMS B. sine wave controllers. (So now I have an extra display!) tomjasz- I agree! I have two other EM3ev batteries that have been terrific. For this...

    Cute Q100 lightweight builds slow mtb, fast road

    motomech- Yep, you pointed out the voltage issue almost as soon as I reported it! And I have *too* many spare parts and a couple of old steel bikes in my shed... but I only seem to be able to ride one bike at a time. ;) chas58- I remember you mentioning that EM3ev built the 36v battery, is...

    Cute Q100 lightweight builds slow mtb, fast road

    Following up on my issue regarding the Q100 cutting out after 5 - 10 minutes using a Luna 52v mini battery. More to come as I have an elifebike controller and a 6 FET BMSBattery controller on the way. I've isolated the issue to the Greenbikekit.com controller and my Luna 52v battery. I've...

    Cute Q100 lightweight builds slow mtb, fast road

    ScooterMan101, Funny, I just re-read your response to my earlier issue regarding the Q100 motor cutting out. I actually use the EM3ev controller you mention with a Q100 on my city bike, with a throttle. (Great combination but it does whine a little vs. the sine wave controllers) . I used the...

    Cute Q100 lightweight builds slow mtb, fast road

    Okay, not ignoring anyone but definitely didn't think everything through. I'll try and cancel the BMS Battery order and replace it with a smaller one. Still can't figure out why the CON63 seems to be failing but I'll swap out the battery this weekend with one that is known to work with the...

    Cute Q100 lightweight builds slow mtb, fast road

    I had an extra CON63. I have another bike with a similar setup to this one (where I did not see any issues) at our beach house and I'm going there this weekend and will bring the bike back to try and swap components around. The pain is I've ended up with different connectors on the controller...

    Cute Q100 lightweight builds slow mtb, fast road

    Thanks, guys. I have tried it with a throttle and I have the same problem with the motor cutting out. I had this setup working on another bike with the same controller and battery - no issues. But the controller on this bike was wired a little differently so it was most likely a different...

    Cute Q100 lightweight builds slow mtb, fast road

    Posting here it seems to be the default Q100 thread. :). I'm having issues with my build where the motor cuts out after about 10 minutes (depending on outside air temps- colder longer and warmer shorter). My recent build was on a road bike where I wanted a clean look and only PAS (I peddle...

    Chas58, Thanks! I know what you mean regarding converting a bike. I really deliberated over converting my Homer but in the end decided that it wasn't that much work or cost if I wanted to change it back to a traditional bike in the future. Hard decisions but I didn't want to shell out the...

    Also, the battery and controller are in the rear bag, sold by rivbikes.com. I had the bag modified by my local shoe repair shop to add a front hole with leather reinforcement for the standard ebike wires. The bike is a rivbike H. Homer Hilsen circa 2010. Classic old school steel, nice lugs...

    chas58, Thanks for the follow-up! (BTW, I loved the picture of you and your bike in the snow in your build thread!). I really like the results so far but it has been cold and rainy here (mostly just the weekends ;) ) so I haven't been able to test as much as I'd like. I ran into trouble on...

    The PAS sensor on your fat bike is the same one that I have for my road bike. I've confirmed that it works by manually moving the magnets over the sensor. I tried the non-drive side for the sensor but it's very, very tight. If I can fit the sensor onto the drive side by removing the third...

    motomech, Yes, that was the start of my build. I'm still at it! :? I did purchase the Q100CST and the small lunar battery. I had everything setup except the PAS. (I added a temporary throttle and the setup works fine.) When I went to add the PAS sensor and ring, that's when everything...

    Long time member here... I'm trying to re-solve my PAS options. What I'm looking for is the best peddle-assistance solution for a road bike. My goal has been to create a peddle-assist road bike using a Q100CST (cassette version) that would give me a boast while, at the same time, pedaling as I...
