    Suntour Seat Post Suspension

    Hi, I purchased a Suntour Seat Post from XX Cycle in France about 2 years ago. I forgot to order the Neoprene Cover. I tired to buy one from Suntour USA about a month after I bought one and the wouldn't sell direct and couldn't provide a USA Dealer. So today I went online to contact Suntour...

    Battery Life... 14S5P Only charges to 56.6V

    Hi there, Looking for some advice on how much longer I can expect my 14AH EM3EV 14S5P to last. Background: The battery is about 5 years old. Nearing 300 Charge Cycles. Always keep topped off to about 90% (57.2 Volts) while storing (Perhaps too high?). Always stored inside about 70 degrees...

    Rounding Sharp Corners on Battery

    Hi, I picked up an EM3EV Rectangle pack. The new design is waterproof (per EM3EV) and looks very durable. The problem is the plastic used to create the enclosure forms some very sharp points at the corners. Sharp enough that I know if it shifts in the bag (Which it fits very tight) it's...

    20 Amp AOT460 or 25 Amp IRFB4110

    Grin offers these two controllers that I'm considering. Close in price. I know nothing about the AOT460. Assuming I only need 20 Amp... am I making a mistake not buying the 25 Amp to get what I assume (but don't know) are better (Power handing) Mosfets? Or am I totally wrong... perhaps the...

    Mounting this Battery Box

    Noco Brand. Good/Bad? Cheap on Amazon (not posting link because don't want accusation of affiliation). Mfg Site: https://no.co/hm327bks It's a Group 27 Size. I'd pack the batteries in foam on the inside. Use a small frame bag to carry tools. The interior Dimensions would allow me to...

    EM3EV New Site Log in Problems?

    Could someone with an EM3EV account log in and let me know if their account information is intact. Please note I am SURE this is NOT anything to do with hacking. It's just something with their new site. I've been trying to buy something all day and first I couldn't log in, then when I logged...

    Using Panier Bag for Battery?

    I like mounting my battery on the rear rack (Use front motors) and this configuration balances the bike nicely for me and I don't have handling problems. I recently purchased a back up battery For extended Range. Battery: 9" x 5.75" x 3.25" 8lbs. I don't always need 24AH of capacity, but...

    Looking for EZEE Hub Motor Dimensions/Drawing

    Can anyone give me a link to a drawing of the EZEE motors and perhaps photos of the motor showing the Cable Exit side? Grin has a drawing, but it's one they did a while back and it's incomplete. Looking for something with more detail and I haven't found one. I'm specifically looking to see if...

    Squigley Washer Purpose and Placement PHOTO

    My Mac 350 and the New Side Exit 500 Watt Front Motor I just purchased both have this "Squiggley Washer". That's the layman's Technical Term... please correct me as to it's actual name. What purpose does it serve? I took these photos. The Mac 350 as I was taking it apart. And the Mac 500 as...

    6fet or 9fet for system under 1200 Watts

    When I bought my EM3EV kit geared Mac Paul recommended a 9 FET controller. His Default Controller is now 6 FET. They are both IRFB3077. From my limited knowledge the 9FET should handle more power and shed heat more easily (perhaps thicker wires too?)... but at under 1200 Watts on a Front...

    9C Motor Surging

    When I apply power to a brand new 9C 2806 the motor "surges" unloaded. I am holding the throttle perfectly still... and this happens at slower speeds and also with the throttle wide open. What I mean by surging is it appears to speed up then slow then speed up then slow in a repeatable...

    Electra Townie Front Fork Photo for Reference

    I'm working on a Townie Conversion. This is the fork from a bike purchased in Jan 2016. So it could be a 2015 or 2016 Model. This bicycle was manufactured in China. The Model is 7D Tall Frame. The fork I believe is steel (At least that's what I saw in the Specs and it's not Aluminum). I am...

    9C Front Motor Questions

    All my Pedal bikes have the brake lever for the front on the left. On motorcycles it's on the right. Yes I'm going somewhere with this... 9C has Disc Brake mounts on the left (opposite side of drive line). So can I assume on bicycles with front Disc brakes (In the USA anyways) tbat the front...

    Looking for a FRONT Torque Arm "C" shape

    I bought a front kit DD motor and I'm looking for a Torque Arm that I can fit over the axle without taking the connectors off. I've seen the DR BASS torque arms, but it looks like they only are made for the rear of the bike. Please reference where I might get something for the front if it...

    Mounting a Controller to the Bike

    This is kind of a boring subject, but I'm currently wondering if anyone has come across some simple mounting options. For example: I like RAM MOUNTS X-Mount System for mobile devices... I use their solution for mounting my POV camera. I'm thinking about trying one for a small controller...

    130mm Rear Hub Motor

    Does any company you have ever seen offer such an option with standard road bike rear spacing? I do not care if gear or direct drive. This is just a simple question. Yes or No. Have you seen one and if so can you provide a link. NOTE: I DO NOT WANT TO HEAR ABOUT STRETCHING FRAMES TO FIT...

    Anyone Purchased a MAC 536HF FRONT Ebike Hub Motor

    Here are the photos. EM3EV says they carry this model motor, but they only order it with a really long cable. God only knows why. Why in the World would you get it with a long cable and kill all the benefits of being able to detach the motor without the hassle of completely disconnecting...

    Probably a dumb question about mounting to rack

    Topeak, Ortleib have quick release brackets from many of their rack bags. Is there any generic quick release system that can be attached direct to a battery case to move it from bike to bike easily? I have different bags on each bike right now and I'd prefer to just use the same bag across...

    MAC 536HF FRONT EBIKE HUB MOTOR vs Bafang G01

    PREFACE: I'm looking to replace my existing MAC 350 Watt Front motor. I bought a kit from EM3EV in 2012. I've got about 3200 miles on it with no real problems, except sometimes it does stall out when starting from a stopped position (Meaning I hit the power and it's a no go until I start...

    Straightening Chainline Recumbent 6' Chain Front Hub Motor

    1. My recumbent has a long... very long chain. When I measure distance from where the chain leaves the back derailleur to the furthermost point of the large chain ring the distance is 72". That's a whole lot of chain (just over 12' of chain total!) Proper "chain line" on this bike is really...

    Bafang Mounting Question Specific to Booms/Trikes/Recumbents

    It appears that the Bafang Units may not be a great choice to mount on the end of a recumbent Boom. But some shops are doing it (I've seen them on Trikes)... and it seems to work. But I've also read about people having problems because of the torque of the motor. I got a reply message from...

    Bosch Yamaha or Shimano Steps Where to Buy?

    Been doing some digging in Google... not much help (I might be doing it wrong). Are any of these Drive Units available as kits for sale in the USA to install on my own bike? I'd be happy with 250 watts. I'm considering mounting on a Recumbent Boom. Thanks.
