3. Handlebar. Chilly has low and wide handlebar that gives stealth look, Insane in the other hand has medium size “ape hanger”. I haven’t had chance to ride with Insane, but sitting position feels much more convenient.
4. Mudguards. Insane has mudguards with our own rear connections. Those connections are designed in a way that you could connect via them mudguards, rear rack, etc.
5. Lights. Although both bikes have LED lights running on battery, then shapes are chosen to match bike’s design.
Other minor differences come from color scheme :)
