List ten ways you could improve Bicycles that are realistic.

• Place a electrical wire-ring system in the bike that would be able to cool down your drink bottle like a chilly bin.
• Build a surround sound system on the handle bars and back of the bike so you could plug in your phone and it would play out loud.
• You could make you bike a WIFI hotspot.
• Hook up a AI GPS.
• Wire in a phone charger but the catch is the faster you ride, the faster the phone charges.
