The motorcycles here are reliable and well maintained. Very few places in Taipei rent large motorcycles to foreigners; most require hefty deposits, often more than half the bike's market value paid a month in advance via PayPal. The motorbikes this rental shop offers are solid and dependable, and their rental deposits are very reasonable. (That's helpful because foreigners who are unfamiliar with local speed limits and traffic rules can be at greater risk of fines.) I've rented from them twice: previously a CB1100, and this time a Vstrom 650 for a week. The owner is professional and very responsive. Although there is no physical storefront, which might be slightly inconvenient for tourists as you need to make an appointment and let them know the ETA. English communication was excellent and they replied quickly, even late at night or early in the morning about my questions regarding the rules and best places to visit or the road and weather conditions. As promised, our deposit was fully refunded one month after the rental. For a friend who rented a smaller motorbike and has a local driver's license, no deposit was required. Fantastic service and a trustworthy owner, highly recommended.
