I did a little more research before this trip and heard good things about Angkor Motorcycles in Phnom Penh. Their motorcycles are known to be road worthy and properly maintained. Furthermore, they promised to put working odometers on all their bikes. Seeing that this trip might get a little tough, I decided that it is better to spend the extra money. Actually, their rental rates were just slightly above that of Lucky! Lucky!. At US$9 per day for Honda Degree 250, it was definitely affordable.
To my pleasant surprise, Angkor Motorcycles provided me with a basic set of bike tools, which would come in helpful if my motorcycle is to break down. I also requested an additional screw driver to mount my Garmin GPS receiver which was provided with no questions. However, I was slightly disappointed when I found out only after riding for 10km that the odometer was not working. I rode back to the shop for repair. No big deal I guess, I was not in a hurry and it was partly my fault for not checking earlier.
I rented my motorcycle from Lucky! Lucky! which is one of two (the other being New! New! and located justed new door to Lucky! Lucky!) Phnom Penh motorcycle rental shops listed in Lonely Planet Cambodia. Lucky! Lucky! is located at 413 Monivong Blvd near Capitol Guesthouse. Their contact numbers are (023)212788 and (023)220988. Alternatively, you can reach them via fax at 012892856. The manager of Lucky! Lucky! is Bunhieng Tang.
Lucky! Lucky! has a fleet of Honda Wave, Honda Degree 250 and Honda XR 250 Baja. For the type of terrain at Bokor Hill, a scrambler like Honda Degree 250 or Honda XR 250 Baja would make better choices. Both scramblers are four-stroked, electric start motorcycles known for their reliability and performance in off-road conditions. Compare to Honda Degree 250, Honda XR 250 Baja is a larger scrambler and not suitable for riders of smaller built. Lucky! Lucky! rents out both models at US$6-9 per day, with the option of adding a helmet at US$1 per day.
