Want to ebike my Niner RIP 9 Full Suspension

I have a full suspension bike I ride on some legit trails Saw-Wee-Kee, Palos and just for a work out with my wife a not legit but still lots of climbing waterfal-glen.

Anyways I don't want an electric dirt bike. I want something that while just give me the ability to keep up. I find that mechanically my right knee and leg can't handle climbs. I'm also good for short huge bursts of power or long decently high even output. If I combine the 2 like my friends I loose out on both after about 45 min to an hour.

I just want something that's capable of matching my wife's climbing prowess almost entirely on its own.

I would never care if it exceeded 20mph unless I was going downhill and I'm usually geared well enough to pedal downhill as is...

So again I don't need much.

I want light weight because of lower power and good value. Will be used on and off road but never to achieve higher than human capable speeds...

Meaning never more than 20MPH on flat land.

I've been looking at the mid drives and want some recommendations on the correct units. Also are there hub drives that have reduction built in that are affordable.

Which play best with pedal assist and what can I buy without pedal assist and add it later?

I'd like overpowered parts that won't break and will probably not run the system at its max voltage. Also I have 2 new DeWalt a123 celled 24V packs and wondering if these would work well... That could be 48V correct?

weight vs power. Choose one.

a light weight low power addition is 10 lbs. Most ebike weigh 60-70lbs. Is that what you want?

If you use more than say 350 watts, the system will put out much more power than you ever will, and thus be essentially an electric dirt bike.

generally, if you want high power and low speed, you need low voltage and high current. a 48v system is going to be pretty fast.

for mountain biking, or anything with hills, you want a Bafang mid drive.

No, batteries like that generally won't work because they almost never have the current capabilities you need for a strong motor.

The problem you will run into with most higher end modern geometry full suspension MTB's is that the BaFang mid-drive won't fit or it has to be mounted with the motor pointing straight down, limiting your ground clearance.

The reason for that is most frames don't have a straight down tube at the bottom bracket. The trend is for the down tube to bend before it meets the bottom bracket. In addition, most carbon frames have too much frame material around the bottom bracket to fit a BaFang.

If you want to build your own BaFang powered "full suspension" MTB it's best to shop for a specific bike that meets the mounting needs of the BaFang mid-drive.

IMO most of the non-BaFang contraptions that people are bolting to their modern geometry full suspension MTB's are unsightly extremely noisy messes. The BaFang is super quiet and has a very clean look with the controller built into the motor. All the "issues" are already worked out, you just have to find a full suspension frame it will fit properly with enough ground clearance. I'm not the one to tell you which ones those are.

Good luck and let us know if you find a mid-drive that will work on your Niner RIP 9 FS MTB. I ride a Santa Cruz Hightower and would love to have a simple hill climbing aid that doesn't screw up the wonderful modern design and weight of the bike. I haven't found one yet...
