Converting a Radio Flyer Classic Trike to an e-Trike Answered

Hi. I've been looking at the Radio Flyer Classic trike for kids and realise it would be the ideal project to convert into an e-trike . Would welcome recommendations and best practice to do this . Component -wise , most important to consider ( slimline battery shape , throttle ( reverse feature) , fixed drive shaft ), front fixed foot holder. This would be my first project on Instructables and would love to document and share based on best feedback options adopted . Thanks!

Assuming this is for an adult and is meant to go fast, you should look into bike hub motors. You can find lots of them on aliexpress.com and they also carry full conversion kits (for a bike, but should also work for your needs).

Hi Randofo. It’s actually for a kid using the existing frame you see so no speed required . Just fun and creativity !

As some suggested, an electric scooter motor will do it, but it might have a bit too much power still for your purposes.

Crudest and easiest DIY solution would be to hack a power drill. This will give you all the power without much of the speed.

IMHO there is not enough space to actually fit what you need.
At least not without a massive workload on modifications.
A hub motor might fit but then again you have nothing to attach it to.
A normal motor on the rea might work too but no room inside anwhere.
Only way out I see is to create at least a new frame....

Hi

I think Rickharris nailed it by suggesting I take apart an old escooter . May we’ll find all the components I need there . Thanks for the suggestions

If you don't have much building experience this is going to be complicated.
HOWEVER: Your best bet in my opinion is to source an electric scooter strip it down and fit the parts to the bike.
Ebay may be your best source if you want to buy separate bits.
For the most part you don't need complex speed controllers a simple on off button will surfice if you get the motor and gearing correct.
