It's a bit pricey ($2600 USD), but an #eBike with a #LithiumBattery can go for anywhere between $500 and $2000.

Meet the #PiPop, the #ElectricBike you never need to charge (because it has no #battery)

It's like a regular bike, but better

By Bruce Brown Published July 26, 2024

"Electric bikes are hot and getting hotter in the U.S. In response, e-bike manufacturers frequently introduce new models, all powered by rechargeable lithium-ion batteries. 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 #supercapacitor 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."

The Manual · Meet the Pi-Pop, the electric bike you never need to charge (because it has no battery)By Bruce Brown

I asked a few months ago, but looks like the replies are gone… What’s a good #cargobike for a newb? Looking to get something 2nd hand, electric assist, and able to carry my 2 year old kid (preferably with a view, so I think sitting at the front is better)?

Should be able to hold a bag or two from the supermarket, be somewhat stable/fun to ride, and comfortable :)

On of the things that bothers me about all the "tire particulates cause worse pollution than fossil fuels" articles is--where were all those articles before the Electric Vehicles sales started taking off?

Electric Bikes better, but Electric Cars are a good *intermediate* step. Service stations that serve Electric and not just gas would help a lot.

Bicycle touring, service stations are necessary stops sometimes. They need to be transformed, not gone.

So, #electricBike people, I have a question. It's more about electric #trikes for people with #MECFS #LongCovid #Fatigue really.

How can I work out how hard it will be to get up a hill? Is there a formula, a rule of thumb? Like pedal assist makes a 6% feel like a 3% or anything like that?

I'd like some idea of how much it will help me get out and about locally before I spend thousands. But I don't know how to know? There's no showroom or hire anywhere near, so test ride is not an option.

@enobacon We have a Yuba Mundo with a Bafang kit, and our electric cargo bike before that was also a kit.

I have bought my last electric kit.

Electric drive systems put a lot of torque on the whole system that standard bikes that they weren't designed for.

With a purpose-built e-bike, everything from the drive-train to the brakes, tires and lights are built with electric in mind.
