Estimating BBS02 range

[toxie]

Hi all,

I just ordered a 36V 500W BBS02 kit from EM3ev, with 36V 16.5Ah bottle battery. I will install this on a Trek Navigator 2.0 (26"). I live in Iceland and my primary goal is long range. I'm about 90kg.

I am in decent cycling shape. What kind of range could I expect from this setup assuming a low PAS level and heavy pedaling? I am fine with going slow (~20km/h) for better efficiency.

Depending on how my range is with 1 battery, I will likely buy 1-2 more batteries to keep in the saddle bags for longer rides. Is that likely to manage 120+km on hilly roads with headwind? (Iceland is famous for its shitty weather

It depends of many many factors but the average is that at 35km/h 10Km of full electric power needs 100Wh flattening

So your battery 36V 16.5Ah = 594Wh = 59Km of full electric power at 35Km/h

So if you do half the job with pedalling you get ~120Km

at only ~20km/h would be further range like 150Km half pedaling and flattening

Depends how much power you take from batt and how much power you put into pedals. So if you wanna get max distance, limit power to 50 W ( or even less). On 50 W it can go 22 kmh with very easy peddaling on flat terrain, I have this setting on my level 1. Then just divide energy of batt by input power, you will get hours how long battery last. (So in your case it should be 11.88h = 261 km range theoretically)

In real it could be 200km, and dont forget capacity of batt goes down with every charge cycle.

Hilly and headwind will dramatically lower it. I did a test, but went often on full throtle for acceleration, lot of peddaling, i made 1670m of elavation and range 68 km. have 625Wh batt.
