    Well 2x Bioenno for $250 is pretty good for the specs. If you go that route do give me feedback and I can reprogram your controller if you want.

    The silver case motor with 11/80 gearing isn't tripping the Dakota LiFePO4 batteries I'm using. Used these batteries for over a year now everyday to commute.
    Roughly $270 for 4x of these

    I haven't found the right gearing + Go Prammer stats for a Torkinator yet.

    Edit: Apparently the 7Ah twin pack is on sale for $218 to make 4x drop in for ESR

      Guess that same company created a e-bike version using different chemistry: (Not bad for ~$110 to try out but likely too low continuous amp)

        I found some used medical grade LiFePO4 batteries. I need to cut the PVC case and move the cells around and then shrink wrap it to fit the Go Ped. Might try next week.

        Specs: ~25V ~10Ah with raised continuous 24A (vs 20A on my current) and a burst of max 2 seconds @ 40A

        Thus two in parallel should give me 80A burst with 48A continuous. Hoping this is tolerable with adjusted down throttle acceleration via the GoPrammer. Today I blipped it too hard and had to walk the scooter to work

          Interested in hearing about your results. After a long and cold winter i am back in the shop and starting up a new build that will be electric too. Looking into those cheap 100+watt kits.

            I have not made the switch just yet. Honestly, still enjoying the ESR as it is. I think my stock chain tensioner is shot and causing the chain to skip under medium to heavy acceleration. Torn between going with the newer style stock tensioner or a slakinator. Also need to regear for some more speed, 13/72 is all torque for me.
            Any updates?

              I went with a Slakinator, but i have the ESR apart as i am switching to some black billet wheels. I also ended up looking into the sprocket sizing and decided to stick with the 13 front but try a 64 in the rear. No testing yet, but it should hopefully get me a little more speed.

                Should give you 3% higher top speed than stock. I am on 11/80 with silver case motor on the HB & 15/72 on the ESR with Tork.
