We’ve had a lot of success in using ebikes for transporting our kids, despite living in challenging circumstances for this: steep country and relatively long distances. Our little fleet of electric bikes has enabled us to avoid a second car (almost unique amongst our parenting peers) and kept our family economy out of trouble during some years of high costs and low income. They’ve also helped build our children’s sense of self-worth and independence.
Parents in affluent countries spend a lot of time and a lot of the family budget on transporting their children around in cars. As well as cooking the planet, “taxi-parenting” has a high financial cost: running a second car costs are in the $5000 to $20,000 per year range, without taking into account the health costs, car storage and parking costs, or the unproductive time spent. I think that there is an even greater cost: undermining our childrens’ capability and engagement in the world. Transport has become a totally passive exercise, with even older teenagers being pushed in 2 ton prams to school each day. We are telling our children that they are incapable of getting themselves where they want or need to go, and disengaging them from the world – how many or our children are also staring at screens while being driven around?
Of course there are risks to children travelling by bike. However the health risks to children of taxi parenting are enormous: look at the declining health of children in affluent countries. Consider also the cost to their spirit and sense of themselves.
Babies and toddlers on bikes
Small children are probably the easiest to transport by bike. Heaps of baby seats are available for attachment to normal transport bikes, as well as trailers. I carried our youngest around in a rear baby seat for a few years, until he was too heavy for me to keep the front wheel on the ground when I was pushing the bike up hill. At this size it was difficult to transport our kids far by bike, until we got the Xtracycle.

Our first electric Xtracycle cargo bike was a total game changer for child transport. Starting when he was 6 years old, Luka travelled 1000s of km on the back of my Xtracycle and had a hoot. Transporting Luka also kept me fit and sane while Erika went back to full-time study.
Luka was around 25kg for most of his time on the back of the Xtracycle. We burnt out one Bafang SWXH hub motor on the slow, steep climbs, before installing a Bafang BPM (which has done 8000km without trouble since then). I attached footrests for Luka, which are important for mounting and dismounting, and give stability while riding. I had intentions to fit rear handlebars, but Luka was fine holding onto either my belt (warming his fingers on cold days) or my seatpost.
Once Luka passed 30kg, he got harder to haul. He also was getting old enough to ride his own ebike, so I made him one. Interestingly, my google searches for info on kids’ electric bikes yielded nothing.
Luka’s first bike was small: 20” wheels and ??cm seat tube. It had a Shimano 3-speed hub with roller brake in the back and a Bafang SWXK front motor with V brakes (brake studs TIG welded on by friend Ian Aitchison).
I designed this bike to be easy to use: Luka wasn’t an experienced rider. It’s been hard to teach our kids to ride, living on the mountain, as there are very few flat places they can safely ride. Thus this bike was the first bike Luka did a lot of riding on at home.

As the bike was something of an experiment, I made a quick and easy battery box from papier mache. I glued (using Bondcrete PVA) a box from corrugated cardboard (from normal fruit boxes), then layered on scrap paper with diluted PVA. Once it had dried thoroughly in the sun, I gave it a couple of coats of enamel paint to make it somewhat water resistant. I used a heavy plastic bag as a waterproof lid. This box withstood many crashes!
To carry the battery box I had to make a custom rear rack. I used pieces of cardboard to mock up the shape of the rack and get accurate dimensions. The rack was fabricated from 6mm/1/4” mild steel round bar – I get it as straight drawn wire, which has a good finish (compared to reinforcing steel). This is easy to weld (with stick welding), strong and easily repaired, even if it is a bit heavy. After fabrication, I paint these racks with standard steel primer and enamel.

Using a front motor ended up being a real problem – which was a surprise to me as I have ridden 16,000km on my front motor, 20” folding bike. With a light rider and a front motor, there isn’t enough weight on the front wheel to achieve adequate traction going uphill, when the road is wet or loose. When the road was wet, Luka’s front wheel would be skidding for kilometres on long steep climbs, making steering difficult. Getting started on our long dirt access road was very difficult: throttling would tend to cause a front wheel spin, making the bike unstable when trying to mount.
Despite the front wheel skidding trouble, Luka travelled 100s of km on this bike, riding behind me, to play dates and wherever we needed to go locally. As Luka was growing quickly at the time, I changed handlebars to riser bars after a few months. However eventually Luka decided the front wheel skidding problem was no good, and we made him another bike with a rear motor.
Luka’s current bike (2016) is a folding bike salvaged from the tip, with 20” wheels, 6-speed derailleur gears and V-brakes. To avoid the trouble of making a battery box I bought a bottle battery with 18650 cells from Greenbikekit.com. The folding bike had a strong rear rack, so the whole assembly was quite quick and easy.
The rear motor works very well: no skidding, so no trouble on wet roads and Luka can even ride up our steep access road – making trips out significantly quicker.
As with all our ebikes, Luka’s bike has mounts for front and rear lights, and carries panniers. As it is a folding bike scaled for a smallish adult, it will fit him though a fair bit of growth. Like all/most folding bikes, the short wheel base puts most of the rider’s weight on the rear wheel, which gives some riders a sense that it is at risk of unplanned wheelies. I may build it a front pannier rack (like I use on my folding bike) to help balance this.
Although the bike is a cheap, steel folding bike, it seems to be quite robust, especially compared with much more expensive Dahons. Hinges and locks for the folding mechanism are simple, robust and look like they would be easy to repair – we’ve had a lot of trouble with these parts of Dahons. Being steel makes it easy to repair or modify, e.g. we could braze or TIG on disc brake mounts if it goes into frequent use by someone heavier (the long steep descents around here wear away rims using V-brakes, and risk tyre blowouts from overheated rims).
Teenagers and bikes

Our oldest, Jasper, has been a frequent ebiker since highschool. In his last highschool year he rode to and from school nearly every day, 17km and over 800m gross altitude of steep slopes each way. This was a success from a range of aspects. For starters we were able to get Jasper to school each day, without buying a second car, and without spending hours each day driving him in it – this would have cost more than the school fees. Cycling helped Jasper develop skills and self-esteem: we were all proud of his daily achievement, reinforced by many statements of admiration by friends and neighbours at his riding up a mountain every day. The big challenges included remembering to recharge his battery every day at school. Samford Steiner School staff understood what we were doing and were very supportive. While at school Jasper used a folding bike, which gave him more options to get lifts with his bike in family or neighbour's cars - especially on the big climb.

Breaking the paradigm
In many communities our patterns of travel have been profoundly shaped by the car, requiring children to be driven around by their parents several times per day just to participate: in school, friendships, extra activities, etc.. This car-dependent and parent-dependent culture, plus the digital screen age, are creating an extraordinarily disengaged and de-skilled generation of children. This is a real challenge for parents who want to take steps away from high car dependency, build a less environmentally harmful and more resilient pattern of life and raise more capable kids who will be able to cheerfully adapt to a less affluent future. Taxi-parenting is a hard pattern to get out of: not only is it reinforced by the infrastructure we live in, but the paradigms of our peers accept this as normal.
Bikes and ebikes offer a strategy to disentangle from the car culture, while maintaining engagement with our spread-out communities. If your distances are big (but not too big) and you have access to safe-enough roads, electric bikes can help families travel through their weekly routine, when walking or push-biking might have been too slow or difficult. They make cycling achievable when you have to carry loads or when you are not feeling athletic. Ebikes extend your capability and help maintain transport, without a car, in communities which have been shaped by cars.
