Shimano, being the drivetrain maker, should understand how to set the proper chain length right for their drivetrain. But apparently not to the internet experts commenting on a photo who clearly never actually took a proper bike mechanics course, or ever read the actual instructions from the drivetrain maker themselves. To me the biggest drawback of that bike is the suspension fork, I had a similar fork on another Walmart bike that I replaced with a suspension corrected steel fork for a better riding experience and shaved a few pounds off of that bike. I'd take a flier on this bike if I had a use for it, unlikely but I might as a bike to leave at my son's place in Texas so I can keep up with him on rides. The HeyBike Mars Hyper is coming in at $1,499. As an upgrade to the original Mars, that’s a good price for the extra capacity and the alloy wheels alone. It’s a 28” bike with an aluminum dual sport frame and a front suspension fork that can tackle a bump or two with ease. The dropouts are fine, lots of brands have not gone to thru-axles on every single one of their XC frame models. The frame is not straight steerer only either unless you choose to build it as such. Its 44mm zero stack headset cup standard top and bottom, you can put a tapered steerer fork in with the correct EC44 lower headset cup. Same as most major brands are doing for their frames.

The idea of buying one and upgrading seems lackluster compared to buying a frame and building it correctly. Worth noting there's nothing on their website indicating the headset standard, so rather hard to research into something that does not seem to be openly published. I see you've taken a more in depth look at this garbage, so I'll trust you're correct on the standards. Seen a guy with a wall mart full suspension rig. With cheese rims, tires made from asphalt, 40lb rig, bouncy springs. I felt so bad because with his efforts and determination he deserved a rugged hardtail with decent tires and a fork that gets it done. Especially when it came to outdoor or action sports.
