Groschopp offers torque arms on right position gearboxes to supply a pivoted connection supply between the gearbox and a set, stable anchor level. The torque arm can be used to resist torque developed by the gearbox. In other words, it prevents counter rotation of a shaft installed quickness reducer (SMSR) during operation of the application.
Unlike additional torque arms which may be troublesome for a few angles, the Arc universal torque arm allows you to always position the axle lever at 90 degrees, providing you the the majority of amount of mechanical advantage. The spline style lets you rotate the torque arm lever to nearly every point. That is also handy if your fork condition is just a little trickier than normal! Works ideal for front and back hub motors. Protect your dropouts – obtain the Arc arm! Created from precision laser cut 6mm stainless steel 316 for excellent mechanical hardness. Includes washers to hold the spline section, hose clamps and fasteners.
A torque arm can be an extra little bit of support metal put into a bicycle framework to more securely contain the axle of a robust hubmotor. But let’s back up and get some more perspective on torque hands generally to learn if they are necessary and just why they are so important.

Many people tend to convert a typical pedal bicycle into an electric bicycle to save lots of money over purchasing a retail . This is usually an excellent option for numerous reasons and is surprisingly simple to do. Many suppliers have designed simple change kits that can easily bolt onto a typical bike to convert it into a power bicycle. The only trouble is that the poor guy that designed your bicycle planned for it to be used with lightweight bike tires, not giant electric hub motors. But don’t fret, that’s where torque arms come in!
Torque arms is there to greatly help your bicycle’s dropouts (the area of the bike that holds onto the axles of the wheels) resist the torque of a power hubmotor. You see, common bicycle wheels don’t apply much torque to the bicycle dropouts. Front wheels in fact don’t apply any torque, so the entrance fork of a bike was created to simply hold the wheel in place, not resist its torque while it powers the bike with the induce of multiple specialist cyclists.

Rear wheels on common bicycles traditionally do apply a tiny amount of torque about the dropouts, however, not more than the standard axle bolts clamped against the dropouts can handle.
When you swap within an electric hub electric motor though, that’s when torque becomes a concern. Small motors of 250 watts or a smaller amount are usually fine. Even the front forks can handle the low torque of the hubmotors. Once you strat to get up to about 500 watts is when challenges may appear, especially if we’re talking about front forks and even more so when the material is weaker, as in aluminium forks.
