Hi,
I would like to electrify my tandem bike. I found another thread on this exact project here and it suggested a Smart Pie motor. But from my research on this forum, that internal controller is not very water proofed inside the motor. Therefore I started a new thread to see what you guys can suggest.
Bike + Rider = 145 kg after electrification, with no cargo.
Here's a picture of my tandem a few months ago. The only difference now is that I have a rack with panniers on it.
I would like something simple to install that looks clean. By looking clean I mean having stuff like a well packaged/hidden controller, water bottle battery, or some kind of nice packaging for the battery. I don't mind doing a little DIY, as I am quite handy, but I do not have access to a lot of fabrication tools. I live in Sweden and my budget is quite low, maximum 6000 SEK = 690 EUR = 924 USD = 593 GBP for everything I need.
Here the terrain is quite hilly, and I would like electrification for a lot of help on that. I would like to be able to average 25 kph on a typical journey, so that would mean being able to go faster than 25 kph with pedaling on the downhills and possibly flat roads as well. I am open to all suggestions, especially from people new to electrification as this will be my first attempt as well
Thanks!
Horace
EDIT: Added more information based on questions asked:
Both riders do not plan on pedaling lots. We usually take it really easy on the hills, low cadence and low effort. We would like to go faster though.
Frame is steel.
Rear frame spacing is 135mm. Front is 100mm.
Rear drop out width is 10mm.
I drew a picture of the rear. the 350 mm measurement is of the tire outer diameter.
Top speed really doesn't matter to me. But average should be around 25 kph. So the bike can either go up hill at 15 kph and downhill at 35 kph, or up hill and down hill at 25 kph. But I think the latter option is better. We would like more help up the hills when times are tough rather than the other way around.
I think 30 km range without pedaling will get me a round trip to pretty much everywhere around town. I would like to do long distance touring later on.
