Does anyone around the Central Coast know somewhere or someone local who can convert my mountain bike (Giant brand 26") to electric assist?

Or is this not a good idea?
I asked my local bike shop and they did not want to know.
That worries me a little. :help:

On a related note Allan, the NCM Prague is an excellent budget e-bike which is on special currently for $1259 delivered: https://www.leoncycle.com.au/NCM-Prague-Electric-Mountain-Bike

We just bought two of them and took the dog off-leash for an 8km run through the forest yesterday. The bikes coped well with hills.

Allan, I have a Lietner Electric Mountain Bike, got it two years ago. Full suspension. I don't think they sell my model anymore, but here is a link to their website.

There are plenty of Ebike sellers online, but they can get expensive. Conversion kits are available for DIY. Rear hub motor conversions might be the easiest, but I have seen front drive versions as well. Ideally, the best of these electric bikes are crank mounted motor models, Bosch makes crank motors ( which usually means you don't have to scrap your existing wheel, like you would in a hub mount.
Anyway do lots of research, and stay with the legislation regarding ebike power, speed, etc. There are some sold which are illegal, and frankly dangerous. If you are going to use it on the road, bike paths, etc, it must comply with the regs. Off-road only have few restrictions.

You could prossibly do it yourself. My wife needed something to get her to work and back without reducing physical exercise to zero, so we got a 2nd hand 26" Giant, a Bafang 350W mid drive conversion kit from AliExpress and some sundry parts like mudguards and put it together in a few hours. You basically replace the crank set, install the battery, cables and a couple of sensors and keep everything else. Cost for the whole thing was around $1.2k at the time, incl. the donor bike. It went together pretty easily, and most of the work was in attaching the battery properly and tidying up the cables. Attached photos of the build in working order but before the cable work was cleaned up a bit. It's now done 6,000km and has not needed anything beyond the usual wear-and-tear items. It's an ugly bast*rd but is robust, reliable and has more than paid for itself.
