Hi folks:
I bought a Yuba Mundo many years ago and have toyed with adding a motor. However, the price of a "legit" build that most folks recommend (bafang mid-drive or, more recently, gmac rear hub) has been holding me back. I haven't used my Yuba much with my kids and I'm not 100% sure that making it an ebike will change that, so I don't want to pour a lot of money into a build that might not get used. I'd like to put together a starter setup for around $600 - 800 that will help me figure out if I want to go big.
Donor Bike: Yuba Mundo (v3? I think). Has been customized (by past owner) with front shock and hydro disc brakes.
Budget: $600 - 800
Location: Marin, CA. Most riding can be flat-ish, but I have to go up a (partially paved) fire road that has about 100 feet of 25%+ grade to reach my house. Ideally I'd like to ride that portion although I can get off and walk if that constraint brings the cost up too much.
Max Speed: Can make trade offs here. 15 - 20mph on flats is probably fine. An ideal situation is that my wife can ride the Yuba at a fast enough pace that it's fun to ride my road bike with her.
Max Range: 15 - 20 miles at 15 - 20mph? Willing to make tradeoffs here.
Wheel size: I believe they are 26"
Brake type: Disc
Rider/load weight: 260 lbs (around 180 lbs for the rider + let's say 80 lbs of kids). Load will mostly be on the back (kids, cargo)
Terrain: mostly flat, but have to deal with that short steep segment every ride (100 feet @ 25%+)
Usage: recreational, realistically probably 3 - 4 times a month. Hoping to ride with kids, rider may be my wife (less confident rider, if it matters)
Priorities:
1. Budget
2. Safe battery.
3. Getting up that hill segment (100 feet @ 25%+ grade). Am willing to abandon this requirement totally if it's impossible given budget.
4. Range
5. Top Speed.
Aware my budget is very tight, but perhaps a cheaper hub motor kit with a $400 - 500 battery from em3ev would work?
Wondering if I should be mostly looking at front hub builds because of the grade I'm trying to get up (when riding it I have to keep a lot of weight over the front wheel).
