Wintergreen Mtn

This was a big test for the bike. I failed miserably but, the bike did okay.

The biggest issue is one I nearly fixed, my tires are huge, I should have put on much smaller lighter road tires.

I was overgeared for the ride I really needed at least 2 more gears worth of range at the bottom. That could be fixed with a smaller crankring.

I do not have the stamina right now to pedal hard for a ful 30 min. I was done with the test in under 10 minutes of steady climbing & 1 mile up a 6.75 mile ride.

The battery & the motor did fine, I could have appreciated more torque for this ride but, that's not available on this motor, it's given up a little torque for speed. Climbing hard for a mile & up 564 feet over that mile in a little over 9 minutes ate no noticeable amount of battery. If I were either geared differently or had a motor wound for more torque & less speed I think I would have finished the ride but, not in nearly the time I had hoped for... "hope in one hand & wash the other." More torque would have greatly impacted the time. Even at a 12% grade climbing more than 1 foot for every 10 foot traveled, the motor had the power to pull by itself at a few mph, after my legs went rubbery I used the override to get to the next safe pull off. The override will only pull the bike up to about 5 mph on flat land by itself.

SO I would suggest that this is not the bike for those who live in San Francisco, the Rockies or on Wintergreen Mtn. It's a bike well suited to the Piedmont topology, for mountain riding I would definitely give up some speed for a lot of torque & on flatland I suspect I could get ranges that would strain belief. 1/5th of the Earth's land masses are mountainous so this bike is arguably well suited to about 70% of the land on the planet. Closer to home I don't think I'd want to put it under a person in Charlottesville VA unless they only intended to ride it around town, anywhere West of there would wear on my conscience until the land flattened back out for the Midwest plains. My next hill test will be a 5% grade on the C&O Trail.

    Interesting. The battery did fine. The torque vs speed tradeoff is a tough one.

      It’s okay I’m seeking it’s limits so I don’t oversell the bike, I need to know it’s limits when it’s being ridden by a reasonably average rider. A 12% grade is too much but, 5% may be fun.

        I see. So you are aiming it at the average rider. That is good. A bigger user base.

          I have 3 aims, the young adult who needs a commuter vehicle but, can’t afford parking, insurance, trying to find a gas station in their city. The urban professional who has a desire to commute but, can’t show up to work stank nasty & drenched in sweat & the fact is they can do their commute faster on a bike than they can by train or car/cab. The one I’m most hopeful for is the retirement market that wants to stay active but, knows they need some help & want to not have to call for it… the old guy can ride a bike but, if he tried to climb the hill down the street on the way home he could have a heart attack but, with the assist he can be far more assured of a safe climb.

          People who want to get normal results from far less input & then to be “superman” with normal effort.

            The older crowd is a good target. Smart…

              The next gen is more affordable sized bikes & a far more lux custom job. I’d like to add to that a higher torque model for hills & one for heavy loads in year 3. After that it’s about recreational mobility equipment to help people who have medical impairments live fuller lives through electric assistance.

            Big plans… I wish you luck

              It’s a ladder one rung at a time.
