    Speed vs battery life

    The Strava data was uploaded from Mission Control after the ride was complete. Here's what I don't get. Calories and watt hours are energy units just like kilometers and miles are distance units. In the ride shown above Strava says I exerted 52 watts for 33 minutes. That's 28.6 Wh. It also...

    Hub, mid, torque sensor

    Been awhile since the last post but I wanted to add my $0.02. "Tossing" a 60-70 # large unwieldy package into your Tesla will be no trivial task. When you tested the Lectric did you actually load it into your car? It weighs 68# with the battery removed. We had two 30# 20" folding bikes...

    Safer together

    I ride some on "greenways", shared paved paths with walkers. If walkers seem to not realize I'm passing I slow way down and sometimes pull off onto the grass. Also say "thank you" when they move to the right to give more room. Gotta say the analogue road bikers are far and away the fastest...

    A fascinating discussion of EV battery fires

    I accidentally shorted a tiny Li ion battery once trying to take apart an old GPS. Very impressive.

    Speed vs battery life

    Just put the free version of Strava on my phone, very interesting seeing the graphs of elevation, speed and cadence. Thanks for the suggestion. Did substantially the same test loop yesterday at my normal riding style - mostly ECO but SPORT or even TURBO going up hills. Coasting down hills...

    Specialised Como 5

    @Ade169 , any word from the shop about your bike's electrical health?

    Hmmm. I’ll give Strava a try tomorrow.

    Speed vs battery life

    Is the kcal data from Mission Control not reliable? Seems it must know the power (torque I provide, pedal rpm) and duration to compute energy.

    Speed vs battery life

    That's almost double my cal/mile. I don't have a heart monitor but it doesn't seem like it goes up noticeably when I'm riding with this 16 cal/mile effort. What was your average speed on that ride?

    Speed vs battery life

    1 Wh = 0.86 Kcak (kilo calories and calories are used interchangeably at least here in USA). 16 cal/mile = 18.6 Wh/mile. My 6 mile test loop = 112 watt hours from my effort. Battery supplied 36 Wh. Mission Control says that was 195% support. Don't have any idea how it calculates that...

    Speed vs battery life

    I just did some speed vs range vs PAS setting tests on my Specialized Turbo Como 3.0. Same test loop in all cases. Bottom line: With moderate pedaling effort (16 calories/mile) in low PAS averaging 10.4 mph the bike consumes 6 Wh/mile giving about 80 miles range. Similar effort (13 cal/mile)...

    Specialised Como 5

    If you record that 1 mile uphill ride in the Mission Control app it will tell you how much energy was drawn from the battery. Let's say it showed 80 Kw and the handlebar display said you had consumed 12% of the battery. 80/0.12=666. So 666 Wh is the actual battery capacity. I believe the...

    Another Turbo Vado Ergonomics Thread

    I had a dolly in mind just like the one in the link, with the height just right to slide the carrier into the cars receiver. I'm thinking of a ramp that folds in half made out of some aluminum "C" channel. I'll post here when and if I actually do this.

    Another Turbo Vado Ergonomics Thread

    Follow-up from my first post last Saturday: Yesterday I rode a size L VADO SL 4.0 on a 2 mile residential loop, then a size M COMO SL 5.0 on same loop, then rode the Vado again. I brought my bike rack thinking I might buy the Vado but, honestly, I didn't love either bike. Then I rode my Como...

    Questions on current Como 4

    I tried another permutation of PAS and pedal power. Same loop but this time TURBO mode but minimal pedaling, cadence in the 50s, aiming for 10 - 12 mph. Could feel a little motor surging as I was putting so little torque on the crank the torque sensor wasn't sure if I was pedaling or not. Data...

    Questions on current Como 4

    Just for fun I duplicated one of the routes I referenced in the Wh consumption statistics in my post #10 above. I pedaled at my comfort level on both rides. I try to keep cadence between 70 to 80 rpm. 100% eco power - my energy input 16 calories/mile; motor consumption 6 Wh/mile; support...

    Questions on current Como 4

    There's probably something wrong with your battery or motor or, less likely, the IGH. I have a 2022 Turbo Como 3.0 (smaller battery, derailleur gears) and can go 50 miles on a charge without paying any attention to conserving the battery. A recent 25 mile ride with half in turbo mode going...

    Another Turbo Vado Ergonomics Thread

    Full disclosure: I didn't mention this above so as to not further confuse my first post but my wife and I each have a Como. Hauling the bikes usually means I have to lift two of them. She is a little intimidated by the size and weight of her size M Como. She for sure will be getting either a...

    Another Turbo Vado Ergonomics Thread

    I watched that video just this morning - thank you. A friend showed me the "lock the back brake" trick last summer and it does make loading easier. Just not as easy as I would like.
