You will receive a verification email shortly. I just love being outside riding! Here at Cyclingnews, we've taken a look at the key points to consider if you are thinking about fitting a conversion kit to your own bike, including the various motor and battery options available. All an EV-maker needs to do to implement regenerative braking is design a mechanism for the current generated by the decelerating motor to flow back into the The other lets the wheels power the motor when the car decelerates, turning the motor into an electric generator. John is a freelance writer and photographer based in Houston, Texas. And each of those motor types are available for either the front or the rear wheel. 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. It is a brushless controller for regenerative braking controller. The latest race content, interviews, features, reviews and expert buying guides, direct to your inbox! That's the approach that Swytch takes but a good system is more than just a motor and battery.

Regenerative braking lets EVs and hybrid vehicles store some of that kinetic WebThis means in principle it will be possible to have a locked clutch version of the SX motor that is capable of regenerative braking and reverse mode like we have done with the GMAC motor . These systems provide controller options for the Phaserunner or Frankenrunner controller models rather than the baserunners, as those controllers better lend themselves to mounting to a bicycle tube and are compatible with higher voltages. 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. [4] When the motor detects braking, it switches into regenerative mode and acts like a generator. The Statorade allow for heat in the motor to escape more easily, increasing by about 30-50% the continuous torque capability, and the temperature sensor allows the system to automatically scale back power before the motor gets hot enough to be damaged. There are also sensors you can mount on hydraulic brake mechanisms too. Most of our bundled conversion kits come with a suitable field-oriented controller. Heres how it works. Geared hub motors usually weight between 2-4kg and are small in diameter, allowing them to remain pretty discrete on the bike. In general, we find that geared motors are most often preferred by people who value their smaller size and weight, who require a hub with good efficiency during hill climbing, and for whom the ability to coast with zero drag outweighs the benefits of regenerative braking. 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.

Without being able to use the traditional freehub system, a rear-hub motor capable of regenerative energy harvesting would be massively expensive. With the recharging potential in single digit percentages, its just not worth it. the hub motor will continue to propel the bike even when your legs can't. There is no downside or tradeoff whatsoever to having regen if you have a direct drive hub motor, and if you have a geared or mid-drive motor it's not an option so there's no point mulling over it. The main advantage of this system is that its much lighter than a hub motor system, since youre not adding any extra motors or batteries to the bike. He is a road cyclist at heart and doesn't care much if those roads are paved, dirt, or digital. When you brake, the kinetic energy of the bike is converted into electrical energy by the motor.

There is a TON of misinformation on the internet and endless-sphere in particular which says you should always choose a rear hub motor and that front hub motors are dangerous/unstable/ill advised. And why dont your disc brakes convert heat and friction energy to support battery capacity? EVs and hybrids are designed to harness some of it to power their batteries. Riding on pavement this only becomes an issue at pretty high power levels (>1500 watts), but when climbing hills on loose gravel or dirt roads, you can end up with the front wheel skidding pretty easily even at fairly modest powers unless you deliberately lean over the handlebars. Our most popular geared hub motor conversion systems are theMini G310/G311or slightly larger SX motorsfor those wanting a lighweight and silent setup, and the higher end GMAC kits for those wanting awesome hill climbing torque and regen. But it is up to you as the person building and assembling the ebike to configure this. The harder you pedal, the more power is provided. Why buy a whole new bike when the best electric bike conversion kits allow you to save money while recycling your current one?

All EVs also have conventional disc brakes that work in combination with the regenerative system for quicker or more forceful braking. But the assistance does not change with your pedal effort, as the sensor only knows how fast you are turning the cranks, not how much force you are applying. 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. With a hub-drive motor, you can theoretically harvest the kinetic energy of an e-bike on overrun. G60 Fatbike Kit: The Bafang G60 is a rear geared hub motor specifically engineered for fatbikes with extra wide rear dropouts. So long as you have a properly installed torque arm so that the axle rotation is not spreading the dropouts, the pulling forces that a motor puts on a fork are WAY smaller than the forces present when slamming on the front brakes or hitting a pothole. The ~4kg motor is available in both front and rear options, and comes prelaced in 20, 26, and 700c wheels with a Schwalbe Marathon Plus tire too. Heres how it works. However, there are cases where running different motors makes sense too. We give the option to select a torque arm with most of the hub motor kits. At the bottom of the guide, we have also added some useful buying advice to aid potential purchasing decisions. Firstly, it would be much less efficient to attempt to turn the power generated by your legs into battery power to then be used for forward motion later. Shengyi with 40 Nm of Tork vs. Bafang with 80 Nm of Tork. WebFind regenerative braking controller with free shipping, free return and fast delivery. However, its also less efficient at capturingenergy than some other options because of how it attaches to your existing brakes instead of directly integrating with them . :/. Spinning brake rotors being clamped, to convert kinetic energy to heat, and then trying to channel that into electrical storage at your battery-pack, is a false economy. Now that you know what regenerative e-bike braking is and what it means, consider upgrading your ride and improving your experience! I recall 750W Bafang motor test results where they measured only 43 Nm. These features are not required for people using the hub motors within their nominal power range, but for those who like to push the envelope a bit they are golden. These hube are Statorade compatible, have a built-in thermistor, and use the new L10 connector standard. Electric bikes are becoming increasingly popular as people look for more environmentally friendly ways to get around. We've tested as many as we can ourselves in real-world riding conditions, worked out how easy they are to fit, and what kind of electric assistance they provide. Regenerative braking turns your motor into a generatorone that returns some power to your battery. Most often you would use matching motors for the front and rear, ex dual eZee motors, dual Crystalyte, dual 9C, and the power would always be split 50:50 between the two motors. It's understandable that you might not want to take on the arduous task of fitting your electric bike conversion kit yourself. Regenerative brakes can be expensive, so youll want to make sure that you choose a kit that fits within your budget. Bath Theoretically, a loaded cargo bike could provide more rolling mass to generate greater friction and heat conversion, but it still wont be nearly worth the investment in technology. var id = str.replace(/[\s']/g, ''); Bath For more information on PAS sensors and Torque sensors, see our guide to Advanced PAS Kits and our more generalLearning Page on Pedal Assist Systems.
