A helmet: Seems pretty obvious, but its astounding how many people actually ride trails without a helmet on, which is like begging for a brain injury. Dont ride without a helmet.You can get a pretty decent helmet for as little as $50 (or up to $300 if you want to splurge). If youre in North America, try Mountain Equipment Co-op (Canada) or REI (USA), or if you're in Europe, Decathlon they have great prices and selection.
