Title: Will the bike start with a push
Post by: Steviescumbag on May 25, 2022, 02:03:14 PM: Hey, in Addition to one of my last topics.
I’m wondering if I can push the bike to a start (if someone pushes me) if I’m having electrical whack on start up which I’m convinced is a grounding problem. Just so I can get it home

Thanks

I wouldn't try to bump start it yourself. Sit on the bike and have someone else push.

I have started mine rolling it downhill when the battery was _almost_ dead.

I recommend the Max-velocity, bum-start method as depicted in video below. In any case, please have somebody make a video of your result so it can be placed in Motobrick.com's instructional archives.

Absolutely. Find a strong person to push you, or a long gradual downhill road.

And third gear. I agree with that.

Steep hills work fine too.

Just not too steep

Post by: daveson on May 27, 2022, 08:30:47 AM: Slightly too steep is still OK if you're extra careful.

Just not too steep

When I lived in Seattle I had the steepest hill in the neighborhood at the end of my alley. (Seattle has lots of hills.) I used it several times over the years to bump start. I prefer a steep hill because it takes much less time/distance to get up to speed for a bump start. You do need to feather the clutch when doing any bump start but that's a pretty basic riding skill.
