I'm trying to build myself the first bike. I use a xiaomi m365 for traveling now, but it has some drawbacks (i have to stop it before every sidewalk, potholes, the brakes are not the best in the world, it's limited to the city etc)
I'd like something for going to work and go out do some light mountain bike / forest trails etc
I'm interested in reliability of both the motor and the cassette sprocket / chain (i dont want to wear them out every 400km).
I dont need more than 30 mph top speed and i will start easy (20 mph until i get used to it)
Budget is 1500-1800 euro. If I can squeeze everything in 1500, fine.. otherwise.. 1700-1800... i'd go 2000 only if the extra 200 would change things a lot..
i checked the Bosch / Shimano / Yamaha systems on bikes, but I find them quite expensive to purchase, small wattage (and expensive to replace ) batteries, underpowered motors compared to bafang
PS. I read the "guide" made in 2015, does this still apply? "For 90% are more people I'd recommend a 48V 1000W rear direct drive kit."
I read a lot in the three-four weeks but this is pushing me into the summer if I want to get the motor / bike and the more I read, the harder is to make a decision
My questions so far:
1) New or second hand bike? Should i get a second hand with a better frame / components or new bike? which one handles better with a motor?
2) What type of motor should I go? TSDZ2 or Bafang? Mid drive or hub? I read more about bafang
3) Should i get less speeds on the cassette sprocket and a thicker chain? 8 instead of 10-11? I saw that with bafang u can't use more than 3-4 "speeds" of the cassete because the chain will be misaligned and you will wear out the chain / cassette)
4) Should I try to find something with 1x10 speeds from the start? If i get mid drive motor
5) What is the minimum shimano level you'd go to? Alivio, Altus, Acera, Deore? Higher? (doesnt have to be Shimano, but it's a system that I understand at this point)
6) How would you budget things? what percentage for the bike and what for the motor / battery? 50-50? get a better bike? get a BBSHD from the start, maybe i'm gonna use it on the next bikes i'm gonna have?
7) I saw some bikes have 73mm bottom braket, others have more.. to be future proof, should i try to buy 68mm or 100mm? i dont like fat bikes, so 120 is out of the question
8 ) MTB or XC or trail bike? I'd go with the first two since in the city i'm gonna be helped by the motor and won't be very inconvenient. Also it's 30 minutes ride to the work on a non electrical bike, i presume it's gonna be even faster with a motor
9) Battery : 48 or 52V? Makes sense to get a 52 and never charge it completely so the batteries last more cycles?
