Q: I purchased this bike assembled, Is there a tool to tighten the handlebar

submitted by AngelaChase - 5 months ago
  • A: Hi there: You will need a 5 mm allen wrench to tighten the stembolts on your bike's stem. Thanks for your question!

Q: does it come assembled

submitted by dew - 10 months ago
  • A: Hi there: Great question! All bikes arrive 90% assembled. You will just need to mount the pedals, seat, and handlebars. The brakes may also need some adjusting as they may have shifted during shipping. Please contact your local Target for their in-store assembly options. Thanks for your question!

Ordered bike and it was ready for pick up same day. It was already assembled which was a major plus! Rode the bike 20 miles so and haven't experienced any issues. Good solid bike!
