1 year old on the battery and I get 100km from it at PAS 6. I am a heavy rider at 250lbs+ though so a lighter rider with higher fitness could go further

Hi Jenny, Yes when I can get my hands on a 52v battery from Aijiu I will be testing it for sure! I know it's in the works. :-)

Hey everyone. Just thought I'd post a brief 1 year followup review. The 25ah battery is still doing amazing. It's my goto battery (I have several) and continues to give excellent range and performance. I've biked about 4500km and most of it was on the 25ah battery. Can't say enough good about...

Not 100% sure but the one on the bottom looks like it is a 13-32 cassette vs the original on the top which is an 11-32 Freewheel (not a cassette). You need a 13-32t or 11-32t threaded freewheel. Does the bottom one have threads when viewed from the back? 13-32 freewheels are easy to find and...

I now have 5 ebikes and 7 batteries. I can say without a doubt the 25ah battery is FAR better than the stock 16-19ah batteries down around the low voltage cut-off. I get useful assist basically all the way to empty vs the 16ah which just goes very weak in the low voltage area. I keep meaning...

BTW Chinese new year holidays are just wrapping up so all Chinese based vendors might be slow on replies right now

Jenny/Aijiu is a safe bet and you'll get top notch cells inside. Other Aliexpress vendors may be ok but it's such a crap shoot unless you can use reviews or do enough investigation to be sure they are legit and that you won't get poorly made product. I can't honestly recommend another...

I believe Aijiu/Jenny can provide the battery in 36v, 48v or 52v (capacity in ah will vary)

The 21700 - 49v x 25ah is the largest capacity for that battery format. It just came out last spring, I've not heard of any larger cases in the dorado format.

Glad you ordered via Aijiu and Jenny, she's amazing. I'd love to run across one of the 440L batteries someday just to see them. I know @john peck has one and adapted it to fit his bike that accepts the longer format. To go from 10ah to 20ah must be amazing. I'd struggle with a 10ah battery but...

Are you sure you have seperate settings for Assist Top Speed AND Throttle Top speed? My canadian bike seems to only have 1 setting

Both the protocol, wiring and connectors are different. Bafang uses a 9-pin and Das-kit an 8 pin connector but they look similar. There's a German site that outlines the Das-Kit protocol but you'l need to understand German.

Thanks for the info. That device isn't of use though for your 48v lithium ion batteries just due to voltage differences and that good/bad/weak gauge is designed for lead acid batteries. Here's a link to a proper capacity testing meter that is cheap (requires some wiring)...

What do you mean a "battery load tester". Can you share a pic or description of it? Might be of use. A 48v battery 13ah brand new in Canada from Leon Cycle Canada is $250 shipped to give you a sense of competing battery prices. That battery will be using Panasonic cells inside so it's top quality.

Basic way to check which is "better" but without a capacity meter Charge each battery fully and make sure voltage is 54.6v or as close to it as possible (assuming 48v bike). If you can wire a basic household light bulb socket to the battery do that and put in an old style 100w incandescent...

I'd enjoy a pic or two of that bike when you are ready to show it off! My son has one of those 2 stroke motor kits on a Trek bike and it works well enough but once he had an ebike he hasn't used it even once except to start it and make sure it works. Combining the two is interesting.

Hybrid gas electric??? What are you up to now John? :-)

Whoa. Doesn't the Milano have a 7 speed sprocket? If so there are more options, we just ordered this one for my GF's Milano. https://www.amazon.ca/gp/product/B07XYPH5BG It's got import fees on it right now but that's just because they have it in the USA warehouse only. Once restocked in the...

Looks correct to me. I don't see why it wouldn't work. Shame they stopped selling the Das-Kit throttle it's well made

The whole website is out of whack. Prices on batteries are same in US vs Canada and bike specs are glitchy
