Mid-Drive Motors: Mid-drive motors are located at the bike’s bottom bracket and provide power directly to the bike’s chain. They are generally more expensive than hub motors but offer greater efficiency and better handling, especially on hills. Friction Drive Motors: Friction drive motors are...
The original Sakae CR touring crankset was included with the bike when I purchased it. However, I did swap out the middle 45T ring for a 39er, to make shifting a little easier, as not everyone is a fan of half-step gearing. These chainrings are now 50/39/30. I also made some o...
Because the uncertainty of the estimated Crr decreases with larger sample sizes, sections containing less than 24 samples were removed from the results. When there is a sample size of 24 observations on a smooth, bare asphalt road, the estimated Crr has a precision (standard error of the mean...
Over dinner, I explained that I really wanted to get down to Esfahan to have a look around before leaving Iran, but that my visa was too short to do it by bicycle. I was planning to catch a bus, train or plane down to see the sights, than zip back here and continue on my way....
For the last little bit I've ditched my multi-tool and my key chain in favour of this Wolf Tooth 6-Bit, which is a slimmed down pair of the8-Bit Pack Pliersthat I use for mountain biking with the added advantage that it locks closed when it's in my pack or pocket, assuming you...

In some embodiments, the drive wheel may be coupled by at least a belt, chain, and/or drive shaft to an axle of flywheel 20. Thus, the rotation of the drive wheel may cause flywheel 20 to rotate. Pedal assembly 18 may comprise any suitable type of pedals 30 such as, for example, ...
A multiple speed bicycle of the coaster brake type has a single drive sprocket and a drive chain in longitudinal alignment with one another. A sun gear is keyed to the main drive axle of the bicycle and rotates with the main drive axle. The sun gear engages a drive gear mounted on a ...
it is the object of the invention to design the multispeed gear of the species identified at the outset in such a way that in case of shifting actions in the driving process it is not necessary to shift the full driving or power take-off force, that smaller structural sizes and weights ...
On the base plate 30 there is provided an axially protruding tab 44 with a threaded opening 45 for the reception of the adjusting screw 10. The entry of the Bowden cable 7 is represented in chain lines. The marking 36 for the adjustment may be seen on the change lever 11. The change ...
