Country Roads

8 years ago

Bad Boy 1 is very light weight & has a solid built fill. I’m riding mine on smooth city streets & mostly back county roads. In the city its very smooth & comfortable riding & fill’s very confident on tight turns. Out on the not so smooth country roads the wider tires help absorb up the rougher roads. I swopped out the pedals for Shimano, Deore XT PD-M8000 XC clipless pedals & paired them with Pearl Izumi, X-Alp Seek VII shoes, witch makes pedaling much more efficient. For day & night safety I have a Nite Rider Sentinel 150 on seat post & NiteRider Lumina OLED 1100 on the handle bar. My computer choice was Cateye Padon wireless. The L.E.D light strip on Lefty fork is good at night for added visibility. Its not bright enough to be a head light tho. The rear flashing seat post light is bright at night, but for day time visibility I would recommend something brighter. The Shimano 8 speed shifts fast & quietly. The belt drive is also very quiet. Your going to need a 15mm wrench, same as a pedal wrench to take rear wheel off. I recommend, PARK TOOL Home Mechanic Pedal Wrench. Front wheel will need size 5 Allen. I recommend, Park Tool 3-Way Hex Wrench hex sizes are 4, 5, and 6mm. 4mm will take seat post off.

Yes , I recommend this product
