There's no need to change the wheel like the Swytch the motor sits on top of the rear tyre and a roller pushes it around from above. John is a freelance writer and photographer based in Houston, Texas. This has enormous advantages in terms of simplicity with no moving parts inside, but in order to achieve adequate torque the direct drive motors need to be fairly large in diameter and heavy. Part of the kinetic energy goes to the battery, and the rest goes to the brake system to generate the friction needed to stop. This kind of control can feel very slick and helps encourage more human power input, since you are made to 'earn' your motor power. The mechanical brakes on a bike can easily overpower a motor if for some reason you were to throttle and brake at the same time. The company focuses on all global e-mobility trends of the future. Swapping the front wheel is one of the easiest ways to convert any bike to an electric bike. As we mentioned before, one benefit is that it can help to increase the range of your electric bike.

Direct drive motors don't have a clutch, allowing them to do regenerative braking, but this also means that there is some motor drag while coasting as the magnets are always moving past the stator iron. To keep it simple, think about it as an amplifier. Different manufacturers will program their vehicles to use this feature at different levels of intensity, so itll feel different than braking in a gas vehicle. The position of the accelerator pedal tells the motor controller how much torque is needed. All EVs also have conventional disc brakes that work in combination with the regenerative system for quicker or more forceful braking. Here are some things to consider when choosing an electric bike kit with regenerative braking: Hi, I am Jonathan Smith. That kinetic energy is wasted as heat, and its one of the reasons why biking can be such an inefficient form of transportation. These are far from impossible, but they may require some tools and a bit of patience. Tesla, for example, used to have two options for their regenerative braking system: low and standard. Shop1102120127 Store. For many kits, once the installation has been completed, it will be an arduous task to remove it again, so one of the questions you'll need to ask yourself is whether or not you want to retain the ability to use the bike as a 'normal' bike. The way that electric bikes are designed takes your pedalling input and turns it into forward motion just like a non-motorised bicycle, and the motor adds a level of assistance based on your output and chosen assistance setting. And why dont your disc brakes convert heat and friction energy to support battery capacity? For rear installations, the motor is more discretely buried with the cogs and pannier bags, and it is possible to run at very high power levels without losing traction. See our motor power info page for more details. When you are actually cruising downhill and pushing current back into the battery there is a lot of heat generated within the battery itself. They are typically between 4-9kg and over 20cm (8") diameter. Most standard Chinese controllers with regen will just have a fixed level of regen when the brakes are pressed. link to How to Make a Bike Seat More Comfortable?

In our opinion, knowing that it's been done correctly and safely is worth spending extra. It really makes for some hard going!Over the course of a single charge, you are only really going to get back about 5% of the overall charge of the battery. Its equipped with a powerful motor and large battery that provides up to 80 miles of range per charge. This allows for you to push the envelope of sustained power and torque output from a given motor without risk of damaging the hub. You have to question, is it really worth the additional weight and the resistance of pedaling a Direct Drive Motor to gain just a mile and a half?The next problem with regenerative braking is that it causes significant heat when charging. GMAC Kit: The GMAC motor is similar in performance and torque capability to the eZee motor, but it has a locked clutch instead of an internal freewheel making the motor capable of regenerative braking too. If a company starts with a clean slate and designs an electric bike, it's easier to keep costs low and integration high. We recommend choosing to convert a bike that has disk brakes as they will provide far better braking performance. Bath Take a moment to think about your current car usage and work out the cost per day / mile, including fuel, parking and running costs. Wheel size: Wheel: Bulk savings: Buy 1. There are many reasons to switch from conventional vehicles to electric vehicles. The amount of power that can be generated depends on a number of factors, including the weight of the bike, speed, and terrain. Aside from extending your potential ride duration and using your kinetic energy more efficiently, regenerative braking also takes a load off your mechanical brakes. eZee Kit: The eZee system is our popular high performance geared motor setup, and has about twice the power and torque capability of the Bafang G31X motor (500-1000 watts), making it better suited for steeper climbs and cargo hauling. Larger vehicles have a better regenerative braking coefficient. With the mass of a train or car, you have a much greater energy conversion through the braking system. The combined mass of a bike and rider is just too low, to generate adequate kinetic energy when braking. Previously we also offered a line of more generic Grinfineon controllers as a low-cost option, but have discontinued carrying these due to availability and reliability challenges.

There are fewer compatibility issues with rear hub motors now that we have more options using cassette freehubs and proper disk alignment, such as the G310 and MXUS kits. By the same token there are meaningful efficiency and conversion losses by attempting to do the same, on a much smaller scale, whilst riding along. * js responsible for adding the anchor links to the page. What is your budget? When you run two brushless motor systems on the bike, each motor requires its own motor controller (there is no way around this) but the throttle signal would typically be split to run both motors equally. Hitting the brakes on a car creates kinetic energy. Many electric bikes now come with regenerative braking, which helps to recharge the battery while youre riding. This comes with an extra cost attached, but the benefit is that you can feel comfortable that the system is correctly installed and your bike is ready for it. If you're struggling to find an e-bike that suits you, then why not convert the bike that's languishing at home unloved? The benefits of a front hub are as follows: The main downside of a front hub relates to the fact that on most bicycles, a majority of the rider weight is on the rear wheel rather than the front wheel, so the amount of traction available on the front wheel is not as high and it can be possible for the wheel to skid out at full throttle. Shengyi with 40 Nm of Tork vs. Bafang with 80 Nm of Tork. But to use a PAS or Torque sensor, you need a V3 Cycle Analyst, which acts as the interface between the various sensor signals and the motor controller, and you should choose the "advanced PAS" kit option to see these. This may feel slower than braking in a gas vehicle, and take some getting used to. WebThe small G311 front / G310 rear motors from Bafang are well suited for those wanting light and discrete conversion for moderate assist levels. You will receive a verification email shortly. However, there are cases where running different motors makes sense too.

Keeping the speedometer needle in the upper half of the charging gauge as you stop will save up the most energy. That's the approach that Swytch takes but a good system is more than just a motor and battery. When you hit the brakes on your gas car, the brake pads press against the wheel rotors and create friction to slow it down. This electrical energy is then used to recharge the battery. There is also generally no problem at all installing a hub motor on a bike with suspension forks, carbon forks or whatever. Bafang G311/ G310 Geared Kit: These are a smallish geared motors that are well suited for people who want a more minimal level of assistance than the eZee hub. . You'd generally choose a front hub for ease of installation and versatility, unless your vehicle design doesn't allow it (eg tadpole trike), or your ride situation would have traction issues (dirt road hill climbing or very high power), or you just figure that, justified or not, you want the motor on the back. There's also a cadence sensor that attaches to your bike. The answer will vary hugely, depending on where in the world you're based, and which kit you choose. but to move a bike quickly requires a lot of power, especially going uphill, and this will limit the ability of small motors to make you move fast.
