Tern A7 Link E-Bike conversion

[billriv]

Essentially, I want an E-Bike kit for power to get up the occasional
hill I may have to climb when riding my Tern A7 Link folding bike
around my beautiful island of Puerto Rico. I need enough power to
help me pedal my 180lbs up any incline or hill.

Most of the time I will not be using any motor assist, so I'm
concerned about using a gearless hub motor, because I understand there
is some drag in pedaling when the motor is not engaged. I also
understand a geared motor does not have this issue, so I prefer a
geared hub motor kit for my Tern bike. Having said that, I do prefer
a front hub motor kit for ease of installation.

My Tern A7 Link folding bike has 20 inch tires. I have a Shimano
MF-TZ21, 14-28T, 7 speed freewheel. The rear frame dropouts are
139.7mm wide (equal to 5.5 inches) and the front fork dropouts are
76.2mm (equal to 3 inches.

Which E- Bike kits would you suggest for my needs?

Thank you for your response amberwolf. Unfortunately at the present time that motor is out of stock at bikes.ca.

ah, well, at least you know they make one that will fit.

if you haven't already, you could ask when they'll get one in, or see if they can tell you who makes it so you can find an alternate source.
