DIY e-bike. Need your opinion/suggestion
« on: May 31, 2017, 11:38:41 AM »

So, after giving up on my trial for purchasing am out of the box e-bike, I decided to build my own. I figured DIY is way cheaper even if I buy all components, including the bike, brand new and I have the flexibility of expanding and replacing individual parts in the future. So I have narrowed down to these options:




Bike: http://mikesbikes.com/product/specialized-crossroads-225303-1.htm
Motor: https://em3ev.com/shop/bafang-48v-750w-bbs02-kit/
Battery: https://lunacycle.com/48v-pansonic-ga-17-5ah-black-killer-whale-ebike-pack-huge-range/




Of course, I need a charger etc. But am I on the right track for picking the parts?




Just some context. My commute is 23 miles one way and I weigh 185 lbs and am 6'0". I need enough charge to get back home everyday and charge at home. Commute is mostly flat. Just one tiny hill with an elevation of about 120ft (I don't consider it as a hill, actually). I will be on bike trails for 90% of the commute.

Oh. I actually built one last summer. Cost me $1700 from scratch. Rode it for 100 miles and then found someone who wanted to purchase from me. I sold it for $1900. :) Then built another one with a used bike. I figured I didn't need the 17.5 Ah battery and a mid-drive. So went with a hub motor and smaller battery. The new one is much cheaper. Overall, a great decision. I have since gotten rid of my car. Happy so far.
