    Best bike for short but hilly rides - possibly with child seat on back

    ------------- I've learned with my geared hubmotor e-bike that even hills I can climb without motor help are not much easier WITH motor help if speed drops below around 6.5mph. This speed seems fairly critical for MY motor, and though my freewheel gears allow good pedal power down to under...

    Optimizing the E-Joe Epik Se

    -------- Psych III, I too have already experienced a leak in the front tube ... no nail or thorn visible, but it was losing 10psi/day. I put four oz of "green stuff" in it, and it seems to hold now ... BUT, when I installed the Green Stuff in the rear tube, the tube blew violently a few...

    Optimizing the E-Joe Epik Se

    -------- V, thanks for the prompt and candid reply. Like many bicycle riders interested in specs and performance, I am aware the importance of bike component and/or total bike weights. Most specs for decent components list weights because the realize it one of the very important attributes...

    Optimizing the E-Joe Epik Se

    --------SO------------ So, how about clearing the issue of just how much your Urban bike ACTUALLY weighs all up, with battery. pedals and everything? As I said, my Epik SE weighed more than the advertised 42 pounds, even after removing the rack and fenders ... in fact, even with the lights and...

    The Dirty Dozen - A 37% Grade Hill Climb!

    ------------ I've been on the hill, its very very steep, and some of it is WAY steeper than Fargo St., which I have also been on. I didn't mention grade nor the view, you did. Don't let Google be your source of "education" against folks with firsthand knowledge.

    The Dirty Dozen - A 37% Grade Hill Climb!

    ---------------------- Well, maybe not a street, but for sure a paved public road is the Waipio Valley access road in Hawaii, and its right at 45 degrees! Only low range 4wd vehicles allowed, but it IS a paved road used by the public to access the beautiful beach at its base. I suspect NO...

    Wider range gearing on Eoe Epik Se

    ------ So, not to leave well enough alone, I was visiting my Buddy's bike shop yesterday to pick up a cool new "mansaver seat" (Ism pro saddle) , and he fitted in a good, slightly used (and inexpensive) Sugino crankset that had a 53T big ring and was 7 ounces lighter. I now have a gear high...

    Quick release latch issue

    ------- I guess I misunderstood, and thought you were RELYING on the plastic piece to keep the latch from opening. I see now you latch is overcentering just fine, and its your plastic "safety" alone that's the issue. Ok, yes, well my "safety" must be bit closer to the frame so it engages...

    E-bike for a VERY extended trip...

    I bet the Surly with that neat geared hub does everything you want and need. I just seems that without lots of convenient places to recharge, the e-bike is more trouble than the added convenience of the motor is worth.

    Quick release latch issue

    ----------------------- The plastic mechanism is to prevent accidental operation of the latch, but has nothing to do with the tightness of the clamping mechanism. The setup works by means of a bolt head that is pulled tight by the camming action of the swinging lever. The bolt head, which a...

    Wider range gearing on Eoe Epik Se

    ------- Correction! I Thought could cruise easily now at 18-19mph o level one, but such is not the case! The flat ground I was going that speed proved to be slightly downhill, and a more scientific test the next day showed a two-way average on very level ground for three miles each...

    E-bike for a VERY extended trip...

    ---------------------- Don't get a bike like the Sand Viper for that trip. I rode a couple of em ... fun around town, and might be fun on wet sand near the water's edge, the poor handling and heaviness is a bummer. The bike isn't all that powerful, and is so heavy to pedal even with no added...

    Wider range gearing on Eoe Epik Se

    I just tested my bike after swapping the original seven speed 14-28T freewheel for a new 11-32T seven speed freewheel from Epoch, and its just what I wanted! I had been a little disappointed to discover my bike gave me issues at both ends of the speed spectrum as bought, but now it seems a near...

    Optimizing the E-Joe Epik Se

    ------------------ Jim, I'm wanting a faster cruising gear to deal with the pedal assist issue ... I've tried using the thumb throttle instead, and its not so good ... too hard to modulate for any distance. The discussion regarding the 9T is getting strange ... WHY stay out of the gear you just...

    Optimizing the E-Joe Epik Se

    --------------------------------- Regarding efficiency, to each his own I guess. I bought MY bike to ride for health reasons, wanting to get more excercise in, as well as to have yet another interesting two wheeler. I have roadtested several fat tired E-bikes, and the pedaling effort was...

    Optimizing the E-Joe Epik Se

    BTW, The Voltbike you mention as a cheaper E joe Epic SE is not exactly like the bike I got. there ARE some differences in the spec's and that I see in the picture. Some differences might help explain the cost difference, others are simply just different (like gripshift vs thumbshift) . One...

    Optimizing the E-Joe Epik Se

    Smaller than about 12T isn't efficient, and it gets worse a lot faster as it gets smaller. I have used the 11T on roadbikes before, when I was already stuck with an expensive 53T crankset, and wanted all the speed I could get with 26" wheels. It's a little rougher and noisier, but a...

    Optimizing the E-Joe Epik Se

    Here's some of my rationale: I'm a retired mechanical Engineer, and have lots of (dated) bicycle experience as well. Although I have seen 9T chain sprockets used on the likes of gocarts and engine-power kits for bikes, its really not such a good idea to to use a sprocket with less than around...
