An E-bike we built in 2 weeks. Top speed is 60 MPH. The acceleration is unmatched. I am often challenged by cars for a race and never been beat. 15 horsepower max Briggs and Stratton motor running at 48V. In this video we compare it to a performance moped. We can not use it to its full potential, for risks of another.... more

Making things is just too much fun so we put this together to get home and back to the shop. Gas just isnt fun to buy anymore. These 4 batteries make the 48v we use. A perm motor and a controller was all we needed. Single sprocket and beefy bmx chain. We messed with different teeth until we found this setup good. Its.... more

This is one of the fastest bench tests on the planet for an electric bike, with proof! At 5th gear we did 93km/h. We are the first in the world to design and make this dual sprocket freewheel to go on most bicycles. The speedometer becomes off- the-scale at 6th+ gear. The tire spins over 100 MPH on 8th gear (160km+)..... more

Here is a unique 36vdc assembly we will be showing you. The top speed has been calculated to be around 60km/h at only 36volts - we hope this proves true! There will be further video's to explain how we mounted everything, and where to purchased parts for this assembly. A couple new e-bikes will be built and for sale.... more

Estimated 120mph+ no load test. This video is crazy! Why there is no reflector on this rear tire - It flew off when close to last gear from so much speed and wind. This is very high performance motor only needing 36v to go really fast! It's a huge savings. The motor still overheats after 10-15mins with the improved 80.... more

here we present to you the e-xtenzo ebike from craftmanshift.com we hope you enjoy any questions we will be more than happy to assist you

A short easy-to-understand explanation for the magura thr series throttles. 5V power = red TPS = green Ground = black LED meter = yellow For the Battery wiring, we use the best guage wire, nascar booster cables! Also, There is now a mini intelligent charger mounted on the dash and permanently wired so all that is needed to charge, is to plug the charger in a 120vac outlet!

In this video we continue our electric bike conversion project and install the battery on the bike.

In this video we begin our electric bike conversion project by briefly looking at all of the components and the bike we are going to convert

We make the e-bike for mobiky
