My Stance 2021 came with a 500Wh.
I simply do a morning ride eat at home(close to some trails)
than go for a second ride after 60 to 120 minutes of charging.
I think carrying a second battery on my back is not safe if i fall.
My understanding is 100% means my efforts are doubled, the system
adds 100% of my efforts.
200% = tripled
300% = quadrupled.
So the more efforts i put out = the more i drain the battery but
i can select lower assist level so i can manage my range.
It is related to the importer/distributer and retailer.
All around the planet the service is not equal.
Take care of your Ebike, avoid washing, that is what i do
and i stay away from trouble.
It is lke playing Bingo. You have no idea what will happen.
Low mileage might mean it is a lemon that spent wayyy to much time in the shop.
Look at Giant reliable and reasonable price.
It is not only forks in my opinion.
Just look at Specialized, Trek and others.
They are asking wayyyyyy toooo much, like pay an extra 2,000$ just for our stickers.
I own a 2021 Giant/Yamaha Stance E+ and the fork is lower level but the price of
that Ebike is a lot lower than any other.
I have no idea about distance, elevation, i only use an old 5$ watch.
After 3 years on Ebikes i found most can be drained in 70 minutes
or stretched to 4 Hrs.
Being a light weight rider i can do 90 minutes to 5 Hrs with my 500Wh.
I moved close to the trails so i can do morning rides recharge...
To me all these numbers mean nothing. Test it, will it do that number? Please report if it is accurate or not. When you talk range please mention your weight.
