I want to add some assistance to a 2006 Dawes Double Edge tandem, 26"x1.75" MTB style wheels with disk brakes, triple stokers derailleur and 9 speed rear cassette, as my wife and I are approaching 60 and starting to find hills more taxing, especially starting off on a hill. We generally cruise with 2 front 6/7/8 rear; 1F for uphill, 3F for downhill.
It is by far used for short local trips of up to 30 miles, but I am hoping that we might do more of longer rides with a bit of assist available, for example to visit parents 90 miles away that we used to do.
It will be UK legal, despite the kid in me wanting to max out!
Budget is limited.
First question is front, mid, or rear?
From my reading so far:
Mid would be best, but I can't think of a way of maintaining the front(stoker) derailleur and rear cassette; getting the same range with 1X set up is going to end up changing the mech and shifters, which is likely to break the budget.
Rear seems to be 2nd favourite but there are comments about having to change the cassette which I don't fully understand, and that is a lot of traction to put down through one tyre.
Front seems least favourite, but mostly because of concerns about weight distribution, handling and traction, but seems much easier to install.
At the moment front hub is at the top of my list primarily because of the ease of installation, plus I think converting a tandem mitigates the issues around weight distribution and traction somewhat, especially if I can mount the battery pack lowdown between pilot and stoker. Plus it keeps the wiring shorter.
Before I get into detailed research on front hubs, can anyone point out the obvious (to you) flaws in this thinking?
