Endless Sphere

So I bought GrinTech's total top line components; gmac, phaserunner, CA3, PAS, 14s6p custom batt. The Regen works like this: the throttle is the proportional activator. When braking, the CA3 senses the brake, any 'throttle' applied whilst the brake is ON, is interpreted as Proportional Regen. Applyi...

Stealth DIY Battery incognito under the rack (14S6P 18650), Phaserunner is SMALL. GrinTech GMAC8t, CA3, PAS (no throttle needed) Phaserunner, 52V14AH, Regen Braking, Motobecane Elite Trail 29er, size 23"frame, added Diagonal battery mount for a spare(52v28ah total) This config does pavement to 36mph...

My CA3 doesn't seem to repeat the motor temperature from the Phaserunner. The Temp reads -39C, LoL. Does yours? No but I don’t have the temperature cable. Anyways given my use (high speed and flat terrain), the motor is not the limitation. I’ve never found it to be even a bit warm after use. YEP! G...

Jil - Nice Ebike!

I too went the the "top line" components of "GMAC 8T (on 29" wheel) + Phaserunner + 14S6P battery + PAS ".

Does yours?

Ahicks, I 'feel ya Man'! I'm pushing 60 myself. Its great that these ebikes can be configured for so many uses and personal styles. Even with full PAS, I still get exercise, contrary to what people guessing what its like might say. For myself, 20mins of cardio on the same bike wasn't much fun. Now, ...

AHicks, "Mostly just to get the bike moving from a dead stop. ". That's an opportunity to increase Range. We humans are good at low speed, high torque, like when starting from a dead start. The MTB as great low gears. My CA3 is programmed NOT to add battery current until I get the Mass Moving, then ...

full acceleration "wheelies", haven't even been close to an issue, thanks.
Its PAS, It doesn't do anything until I pedal...then it Goes.....!

"Motorcycle background" - YES! Very important. Ride like you're invisible! With the 9 level PAS sensor as the "master", the "throttle" lever (i didn't want the twist) is almost always just for Regen braking, so its more natural than one may think. The Regen on the rear is smooth and strong, coordina...

"In the triangle batteries just look too obvious the bike is over powered, IMHO. Better CG being forward, agreed.
The Motor simulator at Grin Tach was accurate. But around here 28mph is the limit and easily reached.

Ebike_BDrew_Nov2019small.jpg My 14S6P pack: split into two 7S6P on either side of the wheel well. Built it integral to the rack in otherwise wasted space. Its all aluminium,so the air flow of the wheel cools the batteries and two BMS(es). The batteries are Gap Welded as 1S6P packs, then interconnec...

Ebike_BDrew_Nov2019small.jpg I just completed my GMAC8T / Phaserunner / Cycle Analyst 3 / PAS 14S6P system on a 21" MTB Motobecane Elite Trail. In Cruise, applying the Regen requires an Ebrake signal to switch the throttle into Proportional Regen mode. That pull on the brake lever stops the cruise ...

Looks like the "System" from this thread (my view only) is: 29er Motebecane Elite Trail hard-tail w/Mech Disk brakes (about 286lbs total per Simulator) 9C RH212 Fst DD Hub Motor 52V 13Ah (option to 72v if needed later) (my DIY 18650 cells) Then the Feature Rich control system: Phaserunner/CA3 - this...

Update: Grin has the Phaserunner controller.
Separate the throttle green & blue wires per the manual and program the 0.8V to 0.0v throttle range to proportional braking in their software suite.
The manual (pdf) and sofeware suite are both free so you can see how this works before you buy.

sleepy_tired, thanks for the quick reply and insights. The CA-3 looks like it IS required to get this setup running. Its fun too. The 9c RH212 Fst simulates close to the GMAC 8t (if I read the graphs correctly) and save about $200usd. looks like about just under 28mph is a max speed, which will prob...

29er; I'm close to buying the GMAC 8T with Phaserunner from Grin. With the 12pole sensor and crank torque sensor for Ped-assist mode. Also, an analog brake sensor to enable Proportional Regen braking to save brakes (and have that Tesla feel). The rides are flat lands at 35-40mph for about 5 miles, t...

sounds like you just saved me (and readers) a few years of researching and a couple pricey mistakes; thanks!

I'll be following those links! cheers!

Thanks for the reply and Voice of Reason. Right, the Magic Pie 5 has been out a while, I'm "catching up".... I like the "clean" potential of no visible controller and just my phone on the bars, look. My goal is a commuter/touring that doesn't "look" like a souped up bike or even motorcycle. I got th...

Seems New Tech is coming available!! Golden Motor offers Magic Pie 5 has the controller built into the hub, and puts the display/control on our smartphone, (one less thing- Forest Gump..or TWO). The there's the two speed hub motor from gMAC And compact axial flux electric motors from Magnax! IM SO t...

Thanks, now I have better "specs" to go Hub Hunting...
Pricey, those Batts!!

So, which PowerVelocity would you recommend for 52v batt 1kw direct hub with Regen and wireless smartphone display (less clutter)? Thanks in advance.
