Slower acceleration and lower top speed. Range should roughly stay the same. I've dropped mine from 16s to 11s and tried any voltage in between but 13s. In my case, top speed went from 50kph to 38kph but big difference is felt when going up hills. As for range, it still does 30km easily as...

9C (72V) kit with the cool Cycle Analyst for me from ebikes.ca. As for batteries, got 8x 4S 5Ah hardpacks from HK. I'm an e-bike noob (but not new to brushless systems and lipos) so I found the CA to be really useful. Also, I liked dealing with a local supplier (ebikes.ca physical store is a few...

Cycle Analyst V3 can do this though I haven't used it yet. I suppose I should start using it as it both safer and makes it easier on components. I really like this feature on my RC speed controllers (punch control and start power):

Same. My commute is 30km (each way) through the greater Vancouver area and I've have no problems, not that I excessively speed or anything. It would be challenging to enforce these laws especially with stealthy e-bikes and the fact that it's not hard for a typical cyclist to exceed 32km/h (I can...

Gorgeous bike! This will be a nice conversion indeed. LiPo would be the way to go because they're lighter/smaller, more flexible and typically cheaper. For your commute, I think 15Ah would suffice. To get 72V, you'd need 18S. So, you could get 6x 6S 8000mAh wired as 18S2P which will have a...

That would be how you would wire to get 18S if you pretend each of those bricks is a 6S. If each of those bricks is a 8000mAh, you just need to duplicate it one more time so you can double your capacity to 16000mAh. Once you have two sets, wire them together in parallel using one of these: You...

No you don't need adapter at all, but you can buy them to make the harness. Here's what I mean (using Deans): Anyway, that's just another option to wire the packs.

72v 15ah is definitely the minimum you need to get what you want or very close to it. Battery is always the tricky part. If it was me, I'd assemble 18S 15A LiPO battery from 9x 6S 5000mAh 20C packs or 6x 6S 8000mAh 30C pacs, with the later being a bit more expensive and simpler but either will...

Indeed very simple, and can be accomplished by using 1 series adapter + 2 parallel adapter.

The bike is reaching 3000km and it's been mostly problem free. I've done some work on the bike and here's how it looks now: Basically, I moved the CA, re-routed wires, installed a suspension seat post, added a better stand and light, and replaced the tires/fenders. Also, I'm currently running...

Last week, took the bike to work after being in storage since Oct. The motor wasn't as smooth as before so cracked it open: Living in the Northwest, should've expected this. So I cleaned it up: Also sprayed this after. Maybe it'll help?

12s2p (10 ah) is a good choice. I started with a 12s2p and that was enough for my commute, which is 30km each way (60km round trip) with quite a bit of elevation changes and charging the batteries before/after each way. Also, I'm heavier and my bike is too probably. So, charging once for your...

Bike (with rack, etc.) before conversion - 15.6kg/34.3lbs eBike (9C 2808, Infenion 72V ESC, CAv3) - 24.5kg/53.9lbs eBike with battery (14s 10Ah LiPos) - 27.5kg/60.6lbs +me - 111.3kg/244.9lbs Relatively heavy hardtail to start with but I like how it turned out. My commute (each way) is 30km...

ESC and LiPos in pannier Moved ESC under the rack for better air cooling. Busy handle bar Result of my ride home today. For comparison, it takes me about 40-45 mins by car with typical rush hour traffic. The bus/train would take longer. The other side of the pannier stores the charger...

Finished the bike last week. It would've been done sooner if the batteries didn't take too long. Also, business trips, moving and 1 month long vacation hindered it a bit. Anyway, here it is... Didn't initially plan on putting the battery and ESC in the pannier but couldn't find a triangle bag...
