Trip planning app

Post by Norab » Nov 19 2018 6:28pm

Hi. I am a total newbie, looking at converting to, and building, an ebike. I live in a rural area and the closest shop is 25km or 16 miles ride. It has a total climb of around 450m (1475') but as the route has several up and down sections, the sum of all the climbs will be a lot more. I am wondering if there is a mobile app that will record the gradient data, as I drive the route, so I can then do the math to determine my best setup. I tried a few altimeter apps but they don't have sufficient granularity to be of any use. Most will only sample every 5 minutes or so. I realize that this might already be answered but, I haven't found the right search terms to deliver any answers.

I use the MapMyRide app, and it tracks all elevation changes, but I am not sure how frequently it samples.

Good Luck!

Thanks, TrikeBirder. I am installing it now and will see how it goes.
I found that a lot of apps need internet connection to function but where I want to ride, there is only cell coverage for the last couple of km of the trip.

For future searches, I ended up using Strava and it worked a treat. Unfortunately, my trip to the pub actually has 710m of climb over 25km. Will I make it there and back with my 400W battery? Watch this space :)

I don't know how accurate it is (garbage in/garbage out obviously), but this is fun to play with:

Battery is in Watt-Hours or Wh, so its your nominal voltage (36V or 48V) times your Amp-Hour of your battery which is your "capacity" of the
battery. If you do not pedal you use up 20wh/km but if you pedal you do lower like 10 or 12wh/km depending on how much you want to pedal.
Your motor could spit out 400W and spitting out 400W for an hour is 400Wh.

Battery - Amps is your discharge, Volts, Amp-Hour (Ah), Watt-Hour (Wh) which is V x Ah = Wh
Motor - Watts, but many people will say their motor is 250W in order to sell it to people in the UK, while it really is whatever motor they are trying to sell, 500W, 1000W so the true understanding of how much a motor can spit out, is the size of the motor, the width of the stator, magnets, winding size, Turn Count. But motor is just Watts. Battery is not watts.
