Groschopp offers torque hands on right position gearboxes to supply a pivoted connection resource between the gearbox and a fixed, stable anchor point. The torque arm is utilized to resist torque developed by the gearbox. Basically, it prevents counter rotation of a shaft mounted acceleration reducer (SMSR) during operation of the application.
Unlike different torque arms which can be troublesome for some angles, the Arc universal torque arm enables you to always position the axle lever at 90 degrees, giving you the the majority of amount of mechanical advantage. The spline design permits you to rotate the torque arm lever to almost any point. This is also handy if your fork condition is a little trickier than normal! Works great for front and backside hub motors. Protect your dropouts – obtain the Arc arm! Made from precision laser cut 6mm stainless 316 for exceptional mechanical hardness. Includes washers to carry the spline section, hose clamps and fasteners.
A torque arm is an extra piece of support metal put into a bicycle frame to more securely hold the axle of a powerful hubmotor. But let’s backside up and get some more perspective on torque arms generally speaking to learn when they are necessary and just why they will be so important.

Many people tend to convert a Torque Arm china typical pedal bicycle into an electric bicycle to save lots of money over purchasing a retail . This is a great option for a number of reasons and is surprisingly easy to do. Many makers have designed simple conversion kits that can easily bolt onto a standard bicycle to convert it into a power bicycle. The only difficulty is that the poor man that designed your bicycle planned for it to be utilized with lightweight bike tires, not giant electric hub motors. But don’t worry, that’s where torque arms can be found in!
Torque arms is there to greatly help your bicycle’s dropouts (the part 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 bike dropouts. Front wheels essentially don’t apply any torque, so the the front fork of a bicycle was created to simply hold the wheel in place, certainly not resist its torque while it powers the bike with the push of multiple professional cyclists.

Rear wheels on typical bicycles traditionally do apply a little amount of torque about the dropouts, however, not more than the standard axle bolts clamped against the dropouts are designed for.
When you swap within an electric hub motor though, that’s when torque turns into a concern. Small motors of 250 watts or much less are often 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 problems may appear, especially if we’re talking about front forks and even more so when the materials is weaker, as in lightweight aluminum forks.
