I've been a fan of these bikes since they came out and now I have the opportunity to finally buy one. I have my eyes on a brand new 2018 Alta Redshift MX for $7000 plus the charger. Are there any known issues with these bikes? I've read about some wirebond issues with the MXR battery packs but haven't seen anything about the regular MX version. The dealer said the bike has all the latest firmware upgrades so should I do it? I really freaking want this thing, but don't want to walk into a bunch of issues if it can be avoided.
