Please email us (info@rideyourbike.com) with your thoughts on this bike.

The Leapfrog has been created with the perfect balance of modern technology and time tested design to yield a dignified, comfortable, and extremely stable ride for urban voyages in all seasons. The components have been selected and matched to keep maintenance to a bare minimum while offering consistent long term reliability. Internal gearing and hub mounted brakes are unaffected by weather and road grit, and the integral lighting system assures visibility at any time. The classic geometry allows the rider to easily reach the ground when stopped, while also softening the impact of suboptimum pavement. The upper body is in a relaxed position, with the rider's head well above most traffic, with no strain on the arms, neck or shoulders. The steering geometry is tuned for nimble response to your slightest whim, while the extended wheelbase adds stability in emergency situations. As a vehicle for urban mobility, the Leapfrog offers worry free durability and comfort in a distinctive and stylish package.

This bike is being designed as the ultimate low maintenance, easy to ride, comfortable commuting bike ever. It is aimed at people that live between .01 and 10 miles from where they need to go. It comes with all accessories (sans bags) that an urban biker will need. Kickstand, Fenders, Lights, Reflectors, Rack, Chaingard, Pump, Spare Tube, Tool and Patch Kit, Tire Sealant, Seat Bag, Front Basket, Water Bottle & Cage and a Bell are all standard equiptment. All components were selected with durability and low maintenance in mind.

We are taking custom orders for your very own Leapfrog. If you are interested call or email Aaron. (206) 938-9795 aaron@rideyourbike.com. Price will vary depending on the overall quality of parts you use and the number of accessories you choose. Or......please feel free to "steal" our idea and have your favorite local bike shop or frame builder build you one. Send us a picture if you do. We will also be glad to consult you on your project!

Frame Dimensions

We modeled this bike after European bikes like Batavus, Pashley only with a lighter/stronger frame and higher quality components. This bike won't be cheap, but will last a lifetime! Target retail price is between $2000 and $3000. The quality, design and value will be much higher than say the latest computer that becomes obsolete within 2 years.
