Regarding this IO cruiser out of Texas, I bought it for $200 + shipping, and it now resides in S.CA. :wink:
This now makes it a 7 Tidalforce ebike (+ one IO"X" frame) family. Though my intent was to use it as a backup "parts" bike, as I already have another IO step-side, and with plans to update the hub to "X" status.
I personally prefer the S750X/M750X/IOX cruiser frames over the smaller IO cruiser step-side. It's of course ideal for women or younger riders.
If the original front NiMH battery hub still has life, you can hook in parallel with an alternative battery (42v-46v) source after using a jumper in the 11/12 "B" battery terminal inside the dash. I use HobbyKing lithium Poly Nano Tech batteries. Two 18.5v/8ah in series (21v), two 22.2v/8ah in series (25.2v) then parallel both packs for 46.2v/16ah 4-pack weighing 9.4lbs. These are currently held in a topeak spring rear rack. The performance and range are greatly increased.
I've since started replacing the dead or dying front NiMH hubs with 26" shimano dyno disc rims and using a Planet bike dyno front LED light with Avid BB7 160/180mm calibers. The weight saving is huge, with the regen braking still working great. And upgraded the front 48t chainring to 53t, and pedals for topend speed.
I rode the Red S750X yesterday for my usual 12 mile cardio ride. It's 6 miles uphill and then 6 miles on a slight downhill ride. My cateye enduro 8 reads distance @ 11.97 miles, top speed @ 39mph, time @ 27:59 minutes, average speed @ 25.6 mph. With a body weight of 200lbs, I'm getting 30+ mph on level ground, with light pedaling, & 27.5+ mph on the uphills. With an end voltage of the pack @ 40.7v. This works for me. 8)
I've now got 20 various ebikes/scooters in the collection, and I'm of the opinion that the dead silence of the TF hub is superior to all others on the market! Though I've yet to try the crystalyte 4080 or BMC V4 @ 72v on my spare frame to compare.
