Here are some Frequently Asked Questions regarding R/C Bikes:

1. Which bikes are most frequently used?
- R/C Bikes have been around for several decades so there are many to choose from! They come in all scales, from micro, to 1/8, 1/5, 1/4... However due to availability they tend to only remain in stock for a limited period of time. It would be a challenge to try listing them all, so please check the links section for places where to buy R/C bikes.

2. Where to buy?
- see links section

3. How much do they cost?
- 1/5th scale electric bikes range from $300-$1000, 1/5th scale nitro bikes go for $350-$1000, and 1/8th bikes are $130 for kits w/o electronics or engines. Keep in mind at the cheaper prices you get what you pay for and will probably end up spending way more than that to get it running decently. Check the setup guide for the basics.

4. How fast can they go?
- Just like in real life, very fast! 1/5th scale bikes are able to go 40mph and 1/8th scale bikes are able to go at least 20mph. The faster you go beyond those speeds however, the more desctructive crashes will be (and there will be crashes!)

5. Which electronics/engines fit?
- 1/5th and 1/4 scale bikes: standard 1/10th car electronics and .12ci or .15ci small block engines
- 1/8th scale bikes: standard 1/18th micro electronics (e.g. HPI Micro RS4, Losi Mini-T)
- Micro: comes with electronics

6. How do the bikes stay up?
- Through the gyroscopic effect of the wheels rotating. Try to hold at least a walking speed or else the bikes will fall over. Loops stick out on each side (called crash bars) to keep them from fully falling over, so if you completely stop you can still get them to stand up.

7. How do the bikes steer?
- A servo linkage swivels the front forks left and right. This shifts the center of gravity the opposite way and forces the bike to lean over. After the bike is leaned over, you control the turn radius by varying the throttle (e.g. slower the speed, the tighter the turn).

8. Can they do wheelies?
- In short, yes! You must use a hotter motor and lower the gearing considerably to create enough torque and lift the front wheel. It will take precise throttle motions to control it.

9. What makes them so fun?
- The uniqueness of scale AND the challenge AND the speed!!
