I dropped mine today picking one of the kids up from school. She hopped on before I was remotely aware she was even ready to get in, and it was like someone kicked it out from under me. Boom. Down.
Aha! sez I. I watched videos in how to do this. I'll just pop it right up.
I readily admit to being lame, weak, and crippled, but when I tried the "sit and lift" technique shown above, there was no way. After a lot of struggling, I got the tires to touch the ground, but was then wore out. A second person came and with his help, we tossed it right up. But just me? Nope.
A difference I see watching the videos is mine (K75s) appeared to fall farther over than what's shown. It looked beyond flat, if that makes sense. No tragkorbs btw. Another is the handlebars might be narrower and allow less leverage, which may not be a big factor, but isn't helping.
Just my hard fought observation.
