😀🚲How can I combine a <a href="https://urbanists.social/tags/supercapacitor" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#supercapacitor</a> pack with a battery pack? Is there a battery combiner/balancer that can do regen? Would it need a whole other circuit to be reversible? <a href="https://urbanists.social/tags/eBikes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#eBikes</a> <a href="https://urbanists.social/tags/EV" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EV</a><a href="https://www.youtube.com/watch?v=BcEXAdPfJsY" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.youtube.com/watch?v=BcEXAdPfJsY</a>

French manufacturer Pi-Pop breaks from traditional electric bike design by using a power source you never need to recharge."The eponymous Pi-Pop electric bicycle, now in the third generation, gets riding power assistance from a <a href="https://kolektiva.social/tags/supercapacitor" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#supercapacitor</a> that charges while you ride. Like most electric cars, e-bikes with geared or direct drive hubs can regain energy on the go from regeneration while braking. An electric motor reverses energy flow during regeneration, directing the flow back into a battery."With Pi-Pop e-bikes, which do not have batteries, regeneration is the only way the onboard supercapacitor gains energy. According to the company, a rider pedaling a Pi-Pop e-bike on flat ground regenerates moderate energy by using a small portion of the rider’s pedaling power to recharge the supercapacitor. Riding the bike downhill when the rider doesn’t need to pedal as hard to maintain speed regenerates more energy than flat ground travel. Applying the Pi-Pop’s brakes restores the greatest energy to the supercapacitor."Supercapacitors have several advantages over batteries, primarily charging and discharging speeds and life span. Supercapacitors can store and release energy ten times faster than batteries. Rechargeable batteries have an expected cycle life of 500 to 10,000 charges, but a supercapacitor can be recharged millions of times. Batteries can deliver power over a more extended period between recharging. Still, the superior speed with which a supercapacitor recharges through regeneration can eliminate the need to plug into a power supply. Reliability of the Pi-Pop"With the Pi-Pop’s supercapacitor energy regeneration system, there’s no question of range per charge because the e-bike recharges when you’re pedaling or braking. You’ll only use more energy than you regenerate when pedaling uphill."The Pi-Pop conforms to the European standard for Level I e-bikes, which means the maximum speed is limited to 25 KMPH (15.5 MPH) with power-assisted pedaling only. The Pi-Pop has no twist or thumb throttle, so you’ll need to pedal for power assistance. The bike’s Aikema electric motor and regenerator are rated at 250 watts and 45 Newton meters of torque. That may not seem like much power, but it’s appropriate given the bike’s roughly 48-pound weight and low-by-U.S.-standards top speed."You can shift through seven gears with a Shimano RevoShift shifter and a Shimano Tourney derailleur, all brand-name parts. The adjustable Zoom front fork has up to 45mm travel, which is certainly enough for a bike that won’t be used as an electric mountain bike and rock jumper. The Tektro mechanical disc brakes with 180mm disc rotors are more than adequate."The Pi-Pop bike is available in one size with a step-through aluminum frame in white with green accents. There are no other frame sizes, styles, or color choices. Fenders, mudflaps, a kickstand, a headlamp, and a rear rack are all standard."If an e-bike that never needs recharging is appealing, you can only buy the Pi-Pop at the company factory on the banks of the Loire River in Olivet, France. The price is 2,450 euros or about $2,600 U.S."<a href="https://www.themanual.com/outdoors/pi-pop-e-bike-no-battery/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.themanual.com/outdoors/pi-pop-e-bike-no-battery/</a> <a href="https://kolektiva.social/tags/Bicycles" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Bicycles</a> <a href="https://kolektiva.social/tags/BikePower" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BikePower</a> <a href="https://kolektiva.social/tags/NoLithiumMining" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NoLithiumMining</a> No <a href="https://kolektiva.social/tags/LithiumBatteries" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LithiumBatteries</a>

According to Euronews, Lelièvre 'designed and patented an e-bike called <a href="https://kolektiva.social/tags/PiPop" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PiPop</a>, which doesn’t use lithium batteries but supercapacitors.'"Lelièvre told Euronews, 'The system gets charged when the ride is easy and when the bike brakes—thanks to engine braking—the energy is given back when needed.'"So, what exactly is a supercapacitor?"A supercapacitor essentially stocks up energy in the form of a slow-moving charge, which can be released when needed. A battery stocks up energy as a chemical reaction. This means that the bike is constantly stocking up energy when ridden on easier terrain, and then using that energy when going uphill, in the form of an assist."According to TS2, 'Supercapacitors, which have been around since the late 1970s, offer several advantages over lithium batteries. Rather than relying on the consumption of natural resources like <a href="https://kolektiva.social/tags/lithium" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lithium</a> or <a href="https://kolektiva.social/tags/RareEarthElements" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RareEarthElements</a>, supercapacitors store energy through electrostatic means. This allows them to stock and release energy quickly, providing instant assistance to riders when needed.'"Unlike many other e-bike manufacturers, Pi-Pop also uses <a href="https://kolektiva.social/tags/recyclable" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#recyclable</a> materials such as <a href="https://kolektiva.social/tags/carbon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#carbon</a>, conducting polymer, <a href="https://kolektiva.social/tags/aluminum" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#aluminum</a> foils, and pulp, thus avoiding the need for rare earth elements in its production."<a href="https://kolektiva.social/tags/TS2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TS2</a> reports that 'the longevity of the Pi-Pop sets it apart from traditional e-bikes. While lithium batteries typically last five to six years, the supercapacitors in the Pi-Pop are projected to have a lifespan of 10 to 15 years. This prolongs the bike’s usability, reducing waste and minimizing the environmental impact associated with battery disposal.'"Another perk to the Pi-Pop bike is that there’s never a need to charge it when it’s stationary. You’ll never hop on the bike and realize you forgot to charge it up."Euronews reports that according to Lelièvre, 'We can’t innovate if we lose control of production. When we talk about sustainable development, ecological transition, and energy transition, we need to provide the jobs.' Lelièvre’s company employs 25 people."Pi-Pop currently produces 100 bikes per month. And moving forward the company aims to produce at least 1,000 bikes per month in 2024."Source: <a href="https://www.bicycling.com/news/a46064993/this-e-bike-doesnt-need-a-battery/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.bicycling.com/news/a46064993/this-e-bike-doesnt-need-a-battery/</a> <a href="https://kolektiva.social/tags/Bicycles" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Bicycles</a> <a href="https://kolektiva.social/tags/BikePower" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BikePower</a> <a href="https://kolektiva.social/tags/NoLithiumMining" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NoLithiumMining</a>
