What kind of handlebars and shifters would you guys recommend on this style of bike? It had flat-ish bars on it originally, but I am wondering if something swept back a bit would be cool/comfortable?
I never advocate for the cartridge, that's just me, old school, etc.
That being said, this question is one of the main reasons why, with a small or large stash of BB parts that can be solved by a good trial and error session, mix and match that is a valuable learning experience well worth the time IMO.
The new crank is unlikely to have the actual info you need as it will fit many applications so it will be up to you.
I would stick with the crank that is on there unless your Mom logs 100's of miles all the time. Most of these cheap cranks work just fine for normal use.
Don't forget about the co-op if you have one, they can usually save the day for this.
I don't think there is anything wrong with that crank aside from the BB issue you have.
