Yeah, especially if the part might be prone to breaking again in the future you should consider other manufacturing options, like making a mould, casting it with a tough 2 part resin, maybe even doing some fibreglass reinforcing. Especially since you say it's on a bike, I assume it's going to be out in the sun. Prolonged UV exposure and the associated elevated temperatures isn't great for a lot of plastics, let alone 3D printable plastics.
When it comes to vehicular stuff, 3D printing can sometimes be more useful from the perspective of making a mould rather than the original part.
Also if you have the original part and can glue it back together, you could just get it scanned. I have no idea how much it'd cost to get something scanned, but there's places around that can do that, might be cheaper than paying someone to do the
CAD to remake it (though if a friend brought me a relatively simple part I'd probably just
CAD it for them for free).
