Hi,
Because of work and getting older, it s harder for me to mtb in those hills and trails...so after finding a lot of inspiration here, I want to build my own! So I hope some of you will be kind enough to help out a newbie!
I have read quite a few example but a lot of people have different opinions on the subject.
My requirements are:
1. Mid drive motor (centralised weight) which can:
- carry my weight (89kg) but I'm ok to pedal don't need thumb drive.
- gear and pedalling power sensor would be nice to manage technical climbs but i guess I could learn to ride differently. I have a background in enduro dirt bikes. I'm not in search of huge acceleration just getting me up there.
- Can be fitted without too much work. I'm no mechanic only have basic bike kits etc...
- doesn't cost an arm as I will be spending quite a bit on a nice bike. I will either buy a downhill bike or an enduro one. Those bikes usually have bottom brakets which are 73+ mm (most dwh are 83)
For example those are the bike I have my eyes on:
https://www.orangebikes.co.uk/archive/2013/alpine-160/
Here is their e version of the same bike (what I aiming for: https://www.orangebikes.co.uk/bikes/alpine-6-e-le/2018)
http://www.thebikelist.co.uk/giant/glory-dh-2009
Used bike like this are often 26'' wheels, whereas 27.5 are recommended to achieve better grip. MY plan is to use wider tires to make up the difference.
QUESTION 1: How much power do I need? If you look at industrial production: bosch / yamaha / shimano motors they are 350w max and use 36v battery so it s not that much...
Reading here and elsewhere this is what I'm leaning towards
A. Bafang (500-1000w): seems that it s the best value, reliable easy to install etc...
B. GNG 1000w: seems to be better with climbs that bafang. Worried about the size of the bottom braket as it mentions 68 only? How hard is it to install this one (controller not integrated)
C. Cyclone: One of the most powerfull one but reliability issues? Hard to install (controller not integrated)?
D. Tongsheng TSDZ2: bafang with a pedaling power sensor? reliability issues?
QUESTION 2: feedback on motor for my needs?
2. Battery:
- I m ok with backpack or frame attached. However those bikes usually have small space within the bike triangle so it will have to be attached to the bottom bar hanging style or custom build (an easy of the shelf solution?)
- Capacity: I m thinking several hours outings so doesn't need something crazy but hill climbing usually needs capacity.
QUESTION 3: feedback on battery for my needs? Would 36v be ok to keep the cost down? I see good kits for £200.
QUESTION 4: What is your advice to source all this? China or local uk?
Any feedback for this project is well appreciated!
