>>1807957I've only ridden a super 73 but don't own one.
All non-euro eBikes are mopeds since I don't pedal unless I need to conserve battery.
73 RX is full suspension and faster, it's on my list but I don't need it right now.
I have the Rad Runner 1 (basically same as 73 z-1, slightly slower and less range than 73 s-1) and a Rad Mini folding for bus/train commuting in bad weather.
I hooked the Runner up with 3 linked batteries. I get 75 miles range non-pedal at 20mph, 150+ miles pedal range at 15mph.
All told with NECESSARY upgrades (brakes 100% need upgrade, lights 60% need, nice to have: suspension seat post, mirrors, blinkers, rearview cam, 12v convertor, tire armor) and batteries I spent $4k on a $1500 stock bike and use $250 worth of bike tools that I already had and a solid bike lock.
That's for long range setup though, town/20 mile range you only need the stock bike with brakes/lights/lock so minimum investment is $1800-2000. Either one is way cheaper than car + gas + insurance and it's way easier to do maintenance yourself. The mostly stock setup is perfect for most college towns or if 80% of your needs are within 10-15 miles of home.
I took the Runner camping last summer in CO,
>rode first 50 miles on bike paths/roads to a whole foods, spent 3 hours half-recharging / eating / buying food>rode another 30 miles of canyon roads to an rv campsite, charged overnight,>spent 7 days fly fishing and camping with 2 more paid rv campsite nights to recharge during the trip>ride home was a straight shot with mostly a very slight downhillSome 73 models have better components, but the 73 z/s-1 vs the runner is a style preference. 73 being more dirt bike / sporty and the runner being more of a cruiser. All frames last 30k miles, battery/motor goes 10-15k miles, brake pads/tires/chains need regular maintenance.
73 z/s-1 vs 73 RX is full suspension, 2x range, and speed. Speed only matters on roads and reduces range, requires a license over 20mph.
