You may have to go and measure a frame to see if it will fit .
I have the same one fitted in a 18" Norco frame and there is plenty room,
my inside triangle measures Drop tube 600 , Top tube 505 & Seat tube 345.
Battery is 350 X 128.
I would say as long as the seat tube inside measurement is310 min and top tube is not less than 460 then should fit.
Thanks Nealth. I don't have the option to measure the bike physically, but I can go on their website and cross reference the measurements you have provided.
I'm guessing you have one of these batteries already.
Would you be able to work it out using the dimensions of your battery and the geometry specs from their website?
d8veh has the 48v one and I have the 36v one, the cases are 09 type.
Comparing the Geo with my bike than they aren't to far apart.
C on my bike is 550,
D is 450,
G IS 730.
K is 302
I would be 99% sure that it will fit quite easily.
By scaling the drawing and using the small size frame, I get a triangle with three sides 425mm, 316mm and 515mm, which should easily be enough. It's only these modern frames with strange kinks in them and suspension units that fill up half the triangle that you get problems with.
