Want to get a reasonably priced conversion for a giant escap

[Humanpoweredelectric]

Hello, Sphereites.

I have a giant escape 3 that I really need to have electric assist on it.
I need it to get to and from jobs, and I need enough power and range to carry myself,about maybe 20 lbs at the most of cargo (backpack) and need the right hubmotor kit and battery(ies) to provide me
a running range of at least 40 miles at 20 mph tops (Seattle terrain 10mph tops steep inclines This is the Seattle area, so it needs to handle hills ( this needs to be taken into account.

I already have the bike, just willing to spend $600 tops on a system that will get me there with those parameters reliably
Need info ASAP!
(Front,or rear drive hub?)
(How many watt hours would I need)
(How far will $600 get (most range for my buck 50 miles @ 15-20 mph with 220 lb rider would be divine)
(Chargers/bms/controllers) included with price.

To get a range of 40 miles, you will need to spend at least $600 on batteries.
Have you considered a gas engine powered bike?

Agreed, if not even more.

A 500w geared motor will do. Mac 10t is one example, but there are others. Run it on 1000w,, that is 48v and 20 to 22 amps controller. That will handle the hills fine, unless you, the bike including motor and battery, and the backpack are much above 300 pounds. Then a 48v 20 ah battery will get you the range you need, at 18-20 mph.

The motor kit is no problem to happen at $600, or close to that. But a really good 48v 20 ah battery will be at least another $600.

The usual all in cost for people wanting a high quality long distance commuter such as you need, is around $1500. You can do it much cheaper, but that means a naked battery that is a pain in the ass to charge and balance, could burn the house down, and a motor wheel that has cheap as hell rim and spokes.

But if you choose a cheap ass 1000w kit from amazon, it will also get up those hills. Just be prepared to care for the wheel a lot because of the cheap wheel build. You can shave that battery cost a lot by being able to charge at work. (which requires a more stable, bms equipped battery) Then you only need 20 mile range, and could get by with a 48v 10 or 48v 12 ah battery.

$1000 all in is definitely possible. But you will have to buy the cheap ass motor kit to get that low.

I know this is damn discouraging, but if you spend the $1500, there is every reason to expect 10,000 miles out of it, before you need a new battery. Compare that to the cost of a cheap used car that constantly needs repairs. at $5000 for a similar distance traveled. Those damn repairs end up costing you so much, it starts to cost more than 50 cents a mile to drive. E bike typically comes in more like 25 cents a mile, after you include several sets of tires, brakes, tubes, etc per year. I tended to get about 2000 miles per set of tubes and tires, on average. brake pads about 1000 miles.
