Just calculated the total mileage I can expect to get out of this pack...: 40k mi or 70 days of continuous riding...
dequinox said:Awesome build! I really want to do a long range longtail also...I'm looking at 60ah TS or Foxx cells for the simplicity of pack assembly. I'm new to lithium in that I haven't been able to play with it just yet
What a range though...and the life expectancy seems on par with motorcycle's and cars before their first major overhaul. Well done sir!
nuvola said:Hi grind,
I've some questions for you?
which is the total weight of your ebike without driver?
have you never tried to go down from high mountains?
I've a 48V60ah lion battery carried by a cargo trail and I've some problem braking on 10% downhill.
my ebike is 15kg(bike)+8kg(9c)+30kg(battery)+2kg(tools)+8kg(cargo)=63kg plus my body.
How do you resolved this problem?
I use a trekking bike which can carry at least 7" idraulic rotor but the breaking power it's not enouugh.
Hello!
The bike is ~110lbs or about 50 kgs.
My breaking power is DEFINATELY enough Here's my recommendation:
Crappy hydraulic disc brakes are < good mechanical discs. I'm using the BB7s which are (arguably) the best mechanical disk breaks you can get (and they are an 8 inch rotor).
What model disc brakes are you using?
nuvola said:I started with a kit by shimano (M486 with a 6" rotor), but I've quickly understood that on hills is not enough.
Than I tried to change just the rotor with a 7" (XT model) but still not enough.
Now I'm tryng to using a 8" rotor (I think it's a shimano deore) but I've problem because my fork hasn't necessary space to mount it!!
I plan to switch to Avid juicy 5 (that I already have it, so no more money spent) to see how much power can I gain.
If juicy 5 will not give me desirable break power, the only solution is try to mount a MTB fork and a real powerfull brake like Shimano Saint, Avid Code all with 8" rotor and so on....
My bike is trekking bike and use to work with 28" wheels, so I need to check if a 28" wheel could have enough space on MTB 26" fork.
Because another problem is using a so powerfull brake with a fork that isn't designed to work with those deceleration.
Just note that actually I don't have a rear brake (I'm still working on it...)

Kudos!

Snap? Ouch. How much does that 5.5KWh weigh?grindz145 said:UGH! I managed to snap the entire left rear side of the xtracycle.... I guess 5.5 KWH is just too much weight for it . Anyway, time to rethink this frame a bit...

I see you needed a track fix at the HS feild

At least it can be welded back together (or brazed). Did it snap at a joint or elsewhere? I'm curious about any kind of frame failures, as they teach me about what to do and not to do on my own stuff.
Pics would be nifty, too.
