Well I'm back again.

My father has been asking about a motor for his bike again. He wants to get the exercise but unfortunately he's heavy and we live in a steep valley. He simply can't get out of the valley under his own power.

I'd really appreciate some help with the following:

- Sun X3 SX trike
- Electric motor. Don't care what kind as long as it's not too complex.
- Power is much more important than speed. It needs to move a 280 lb rider.
- His last set-up was heavy! I'd like to save some weight if possible but I assume SLA is still the way too go barring Li-ion prices.

He used to have a 2 wheel recumbent which I had installed a 16" hub motor on the front. It worked well but the weight of the hub motor made it steer poorly when not in use. I think though that with a trike this will be less of an issue.

If this is your trike, I would look for a front electric hub motor kit. The one in the pic has a gas motor but it looks like the installation would require fabrication.

The trick new setup for electric bicycles/trikes these days is the BBS02 Mid Drive Conversion kit. It is a bottom bracket replacement and works on 90+% of all bicycles out there. It is easy to install and comes with a display and water resistant snap together wiring harness - also has brake levers with switches to turn off power when the brakes are applied. Pare it with a 48v-10Ah+ battery and you are good to go.

You can get one here:

They come in a 36v (350W) and 48v config and I recommend the 750W-48v BBS02

I'd suggest looking at the site for Golden Motor (one of the advertisers here) and consider a front wheel hub motor Should be a way to carry the batteries low behind the seat or under it.

Thanks everyone, he's more keen on gas now! Geez this is hard.

The weight and cost savings are a major factor. Just can't swing nigh on $2k for a Li-ion kit.
