Electric bikes are the most energy efficient electric vehicle on the planet, capable of travelling up to 40 times further per kilowatt hour than a typical electric car.
That's means with 1kWh an electric bike can travel the equivalent distance from London to Nottingham.

All trips in London up to 30 minutes are more than twice as a fast as on a bike than motor vehicle and goes some way to explain the growth in micromobility across London.
On a regular bike - it’s possible to travel 10km in 30 minutes. Whilst 10km isn’t far, 74% of all car trips are less than 10km.

Over the course of a year, 1 SQM of solar panels can generate enough energy to power an E-Bike for 45,000+ miles (73,000+ km).

Where are the shared cargo bikes in London when you need them?
Would save me 20mins right now and a lot of heavy bag carrying 🏋🏾♀️

Glorious day for a quick lunchtime haul - transporting a baby and 120 litres of bark mulch back from Croxted Road Garden Centre (3.6 miles round trip - equivalent to 54% of all car trips).
🚤 Faster than a car.
💸 Cheaper than a car.

Turns out it is possible to transport an old bench to the recycling centre without a car. Also faster and less messy 💪🏼

Given that you can fit around 18 to 20 Lime bikes into the same space occupied by a motor vehicle and Lime reported 4.5 trips per vehicle per day back in 2020 - that's 90 trips being enabled versus 0 to 4 for the motor vehicle.
Also enabling mobility at a much lower cost for hard-working people.

In 2019 I conducted some research in Hackney and Southwark asking residents what they'd most like to transport on cargo bikes.
After children (72% of participants) and shopping (25%) - it was pets (4%).
Here is a dog in a cargo bike wearing a Christmas jumper (Jan `25)

"While China pollutes with impunity" - except that China reduced their YOY emissions by 0.5% vs USA who increased them by 1.3% largely down to surface transport. 🙈 🤦🏾♂️

I would be very grateful for any photos people have of the comedy (i.e. not ideal) ways they are currently having to store electric cargo bikes (or E-Bikes) in London.
This will help with a pitch to councils! 🙇🏽♂️

4/ It has space for 2 humans. This also freaks people out.
💡65% of all car trips in Europe only have 1 passenger. Around 85% have 2 or less passengers.
Importantly it has a perfect storage place for a @bromptonbicycle.bsky.social for multi-modal journeys.

2/ For some context, a Tesla Cybertruck/Tank weighs as much as 6 of these (3100kg vs 485kg).
It's battery is over 22 times smaller (5.5kWh vs 123kWh) and therefore uses 22 times less rare earth elements and other materials.

1/ First ever drive in an L6e vehicle today - the
Citroen Ami.
Been wanting a test drive for a couple of years as this class of vehicle can be used for at least 25% of Europe's current car trips.

6/ This is London and it's street parking. If I drive a car, I might need to park somewhere down the road and haul these 5 MASSIVE bags to my home.
When you are a total weakling like me, I can drive my E-Cargo bike up to my front door. Woohoo!

Thank goodness 😅

4/ Hang on a minute though. That's a FULL shopping trolley. There is no way all this stuff is going to fit on a bike. 🚲
