Tailwind II

Mid Level Electric Assist Tandem

Available with road or mountain bars.

Built with the powerful OLI Move motor.  The Tailwind II is a more budget friendly electric assist tandem. Like our Tailwind, it is not a motorcycle and you still get the full cycling experience. The motor is quite, smooth, powerful (80nm), and very natural feeling. The high capacity Li-Ion, 522 Wh, battery last for many miles.
*** This is also available as a frame kit for existing da Vinci owners. You use most of your parts to save money and upgrade to electric assist. Click here for details.
