Become your own Steve Zissou with the U-Boat Worx C-Explorer 5 ($1.5 million). Available in both 100- and 200-meter models, the C-Explorer 5 is a five-person compact submersible that lets you explore the sea depths in dry comfort. Features include a smart deflatable ballast tank system, air-conditioning, up to 43.2 kWh of battery capacity, a 360-degree acrylic pressure hull that allows for amazing views, and a below-surface cruising speed of 3 knots. A perfect complimentary toy for your private yacht.
We're not really sure what, if anything, it has to do with snowmobiles and ATVs, but we can tell you that these Polaris eBikes ($3,000) are far better for urban travel than either of the aforementioned options. Thanks to Biosync Pedal Assistance technology, the bikes can read your power output when pedaling normally and match it to give you an efficient, comfortable ride. Features include 8-speed gears, Tektro brakes, Suntour XCT front suspensions, 26" Kenda wheels, 6061 aluminum frames, hand throttles for extra speed, top speeds of up to 20 mph and ranges of 30 miles, and in-frame batteries that recharge in 4-6 hours.
We've seen plenty of golf carts before — but this might be the first that can actually get you not just around the course, but to and from it, as well. Street-legal in Europe, the Garia Mansory Currus Golf Cart ($80,000) takes the already impressive Roadster and takes it into sports car territory thanks to extensive customization. Features include an adjustable setting for maximum motor braking and battery regeneration, a speed switch with three different driving modes — Golf, Street, and Race — a range of 37 miles, a top speed of 37 mph, and exclusive accessories like carbon fiber inserts, custom seats, a matte black paint job, and black wheels. You'd best hurry if you're planning to park it in your garage — only seven are being built.
