I want to add an electric motor to my recumbent bike, but I am confused as to all the options (motor type, battery type, controllers, voltage, etc). I ride 25 miles to work, it takes me up to 2 hours. I need to increase my average speed to 25 mph to make a daily commute reasonable, hence my desire to add an electric motor. I intend to pedal as well.
Bike: Thunderbolt recumbent (Lightning Cycle Dynamics)
Wheels: 20x1.5 in the front, 26x1.5 in the rear
Commute: 25 miles, mostly flat terrain
Target Kit Cost: around $500
Technical/Mechanical skills: medium
My initial thought was a front hub motor (for ease of installation) with SLA batteries (to keep the cost down.) After a year with the SLA, upgrade to lithium batteries if I'm still using the bike. But other than those general choices, I don't know about motor manufacturers, motor power, battery requirements, controller types, throttle types, etc. There seem to be many choices and I can't tell what's best for my case. I appreciate any advice you may want to share. Thanks!
