ProX Full Suspension E-Bike Frame Bafang M620 Carbon Frame

图片
  There are many options of carbon e bike frames designed for Bafang M510 motors in the market, but the option for Bafang M620 motor ebike carbon frame is still quite limited. Fortunately, now ProX has such  Bafang M620 carbon frame  PXE28! PXE28 is designed to fit Bafang M620 motor and Bafang BT F15(640Wh) or BT F25(820Wh) battery. Bafang M620 is with max torque of 160Nm and with rated power 750W (or 1000W). Such great power enable e-bikes carry heavier load and conquer steeper mountains. In addition, it is designed with dual sensor, which enables riders to have great control of the bike and enjoy sensitive responsiveness all the time. Bafang BT F15 or BT F25 batteries include large capacity and are able to take you further without range anxiety. PXE28  carbon ebike frame  is designed with Horst Link 4-bar virtual pivot suspension system. Rear shock placed in the best balance point to form an efficient suspension system which is nimble, not overloaded and extend the service life of bi

What is the difference between Gravel and CX bikes?

  Without looking carefully, it is difficult to distinguish  gravel bikes  from  CX bikes . Both have road bike handlebars, off-road tires, a more rigid frame and wider tire clearance than their road bike counterparts. So what is the difference? 1. The difference in usage For competitions, UCI has specific rules to manage the manufacturing methods of CX bikes. At least for now, gravel bikes are not subject to any UCI rules. For example, to participate in UCI-approved CX bike competitions, the bike tire width must not exceed 33 mm, so CX bikes rarely provide clearance beyond this range. Unlike  CX bikes, gravel bikes  are usually designed for a variety of purposes, from multi-day bicycle trips to multi-terrain riding near home, and even emerging small off-road venues. 2. Frame geometry difference The geometry of most  gravel bikes  cares more about comfort than cross-country CX bikes. They are designed for riding for days rather than a period of time, and are used to cope with more rugg

Which Freehub Should I Choose For My Cassette?

图片
  As technology advances, we have witnessed the evolution of bikes from 8/9/10 speed, to 11 and 12 speed. Nowadays, 11 and 12 speed are the mainstream for  carbon road wheels  and  carbon MTB wheels . During this process, the freehub body of hubs have also evolved so as to match new cassette or free wheel. Thus, the compatibility of freehub and cassette is becoming more and more complicated . In this blog, we summarize the freehubs that are widely used on carbon bike wheels in the market, and explain their compatibility with cassette. There are mainly 3 brands available for road wheel freehub, Shimano, Sram and Campagnolo. Shimano HG 10/11-Speed Road Freehub This freehub is designed for road 11-speed cassette. It is compatible for either Shimano or Sram 11-speed cassette. Besides, it can also fit 10-speed cassette by adding a spacer (1.85mm). Campagnolo 10/11-Speed Road Freehub Campagnolo system is quite different from Shimano and Sram. Campy freehubs are only compatible with Campy cas

Do you need ceramic bearings in carbon gravel wheels?

图片
  For many riders, the first concerns might be to improve aerodynamics or reduce weight on carbon bike wheels, while friction is usually an overlooked factor. Currently most of bike hubs are with regular bearings made from stainless steel, while our  ProX 98DB disc hubs  are equipped with ceramic bearings. The greatest advantage of ceramic bearings is lower rolling resistance. Because ceramic bearings are rounder, smoother and with more uniform size than traditional ones. In that case, the friction will be reduced and that can contribute more energy to the wheels while riding. A ceramic bearing is also harder than steel bearings (up to 30%), which improves durability, and they will not rust which requires less maintenance. Why ceramic bearings hubs? - Rounder, smoother and with more uniform size to reduced friction. - Harder than steel bearings which improves durability. - Less maintenance(don’t rust), ideal for the riding throughout the year, regardless of the weather. - Affordable pr

Carbon Road Wheels Disc Brake VS Rim Brake

图片
  Since disc brake bikes are allowed to be used in UCI racing, disc brake has been the mainstream in the market. Some riders may doubt, should I go for disc brake or stick with rim brake? To answer this question, let’s compare the advantage and disadvantage between   rim brake   and   disc brake carbon wheel . Generally, the main difference between disc brake and rim brake is where the force is applied. In disc brake system, disc rotors are mounted to the hub (either 6-bolt or center lock), and calipers are mounted to frame (on chainstay) and fork (near bottom). During braking, the force is transferred to the brake caliper and it squeezes rotor to stop the hub attached to it rotating. In rim brake system, brake calipers are normally mounted to the seat stay (or under bottom bracket) of frame, and near the top of fork. During braking, the force is transferred to the brake caliper and it squeezes brake track of the rim to stop its rotation. Advantages of disc brake: - More friendly to th

How to brake correctly for novices?

  How to properly brake on a bicycle is probably the most basic riding skill. Of course, you may think that just by squeezing the brake lever, the brake pads squeeze the rim (or disc brake discs in many cases), the bicycle slows down and stops. But if you have ever experienced fishtail braking, brake failure, skidding or turning, you will know that the meaning of braking is much more than that. In this article, let's talk: how to use the brakes correctly and how the brakes work. 1. The center of gravity shifts back When you brake, move your body's center of gravity back and keep your center of gravity on the rear wheels. This will balance the braking force. If you have to brake strongly at high speeds, this can also prevent you from a front flip. The faster you brake, the more your center of gravity should move back. When you put your butt behind the seat cushion and your belly is on the seat cushion, doing so will give you a huge improvement in braking power and car control. 2

Why We Choose Gravel Bike

Gravel bike is a drop bar bike that you can ride on many different surfaces.Dropping handlebars and road-like bike designs mean you can make good progress on the road. Gravel bikes can be used off-road, gravel road, dirt road, fire, and even monorail. Gravel bikes are suitable for all kinds of road and off-road vehicles. They are designed to be fast on asphalt,but also capable of handling technical off-road drops and narrow monorail. The versatility of gravel bikes makes them ideal for long-distance endurance cycling, varied terrain, and even bike packing. On a gravel bike, you can connect different surfaces, paths and routes in one ride. The gravel bike's drop bar and frame geometry make it fast on flat surfaces, including asphalt. The real advantage of gravel bikes is that you can change tyres and install bigger   gravel wheels   and tyres, allowing you to improve grip and comfort on the bumpiest tracks. In other words, you can turn it into a fat bike! Finally, gravel bikes can m
