    Good tip. Thanks!

    Waterproof wire nuts vs soldering connections

    Looking for a sanity check here.... For electrical connections tucked away inside my EEB frame, would waterproof wire nuts suffice (as opposed to solder + heat shrink)? Using wire nuts may be a easy way to expedite my build without sacrificing functionality, durability, and safety. However, I...

    Bent rim walls ok to ride?

    Friends- Today while mounting some new tires I managed to bend my rim walls. Because the rims are still perfectly circular and true, is this simply an aesthetic mishap, or are there safety/performance impacts that I should consider before riding? These rims are on a 3kw EEB. Sanity check...

    Elegant solution for 72v main power switch

    I definitely see the appeal of this approach. 20-30kw? Wow, that's serious power! What voltages are these builds operating at? I'm using a Phaserunner on my 72v build and the remote on/off for that controller is at battery voltage (but with very low amperage), so one of my challenges is...

    Remote On/Off Switch for Phaserunner V2

    Wow. Lots to think about here. Regarding the OP's original question, would stepping down the voltage with a DC-DC converter be an option that would enable the safe use of low-voltage switches for on/off-ing the phaserunner? Or is maintaining full battery voltage in that connection required for...

    Elegant solution for 72v main power switch

    Friends Can anyone suggest an good solution for a main power switch for my 72v build? I was thinking of adding a DC circuit breaker between the battery and controller, but perhaps there is a more elegant solution? The really slick options such as solid state push button switches seem to be for...

    Hub motor selection guidance: 3kw unbranded vs 5kw QS

    Excellent thought. I'll be using a Phaserunner with CA3 in this build, so I'll take a look into the configurations along these lines. Thanks.

    Hub motor selection guidance: 3kw unbranded vs 5kw QS

    Took measurements this evening and turns out that the 17" rims will fit much better than 19" rims in terms of both width and diameter, even with the wider tires. So there we have it: 17" wheel set with QS motor prevails! Thanks everyone for your wisdom and counsel. Couldn't have broken out of...

    Hub motor selection guidance: 3kw unbranded vs 5kw QS

    Shinko provides a fairly comprehensive tire spec sheet. Time for me to do some caliper measurements on my EEB frame.

    Indeed, which is exactly why value the ES community's input on these matters.

    Hub motor selection guidance: 3kw unbranded vs 5kw QS

    The example you reference is on 18" rims and radially laced. Because I'm considering cross-lacing on a 17" rim, this may be an apples and oranges comparison. Thanks tho. I'm planning on using Shinko 244 tires. They come in 3x17 and 2.75x19, so I figure that would work fine in either scenario.

    Hub motor selection guidance: 3kw unbranded vs 5kw QS

    Thanks for the input everybody- really helps frame my thinking. So I guess I'm leaning toward the QS option now. Future proofing is never a bad idea. Next question would be whether I should use 17" or 19" rims. I'm fully aware of the torque vs speed tradeoffs, but considering the outer...

    Hub motor selection guidance: 3kw unbranded vs 5kw QS

    Nice to see some activity on this thread. Thought it may have fizzled. Single speed is the only way I go because there's enough stuff crowding my limited handlebar space that I don't need to add a shifter up there too. Also, I find derailleur tuning to be horribly tedious. I can do without...

    Hub motor selection guidance: 3kw unbranded vs 5kw QS

    I actually anticipate that my final build will weigh in at over 100 lbs since I'm using an EEB frame and looking to incorporate the largest battery that will physically fit (upwards of 20s10p).

    Do you think a 10 lb reduction in weight would make a significant difference in your experience?

    Hub motor selection guidance: 3kw unbranded vs 5kw QS

    Friends... I'd like some guidance selecting between the following two hub motors (both offered from em3ev): 3KW Rear Direct Drive Hub Motor 5KW QS V3 Rear Direct Drive Hub Motor I'm shooting for a 3kw build, so the 3kw option above seems logical, but it's an unbranded motor which makes me a...

    Remote On/Off Switch for Phaserunner V2

    Another option would be to use a simple snap-in rocker switch with a small electronics project box that your mount somewhere on your rig. The tricky part here is that most rocker switches are rated for vac, but I did find a handy conversion matrix for dc applications that is easy to understand.

    Properly paring motor and battery voltage

    Friends The original idea for the project I'm currently planning out included a Phaserunner, 3000w QS hub motor, and a beefy 72v/34Ah battery pack. The plan was to govern the output to 3000 watts max via Cycle Analyst to give myself the peace of mind that no matter how hard and long I run the...

    Powering lights with Cycle Analyst / Phaserunner

    Thanks for the clarification. Looks like I'd be well within the 1A threshold. I read in another post that the point at which you tap the battery main will affect how the CA displays power consumption. That member was using a shunt with a non-Grin controller, so I was fairly certain the issues...
