Enjoying your TST Surfer step-thru eBike

I purchased this E-bike for my wife that is 5’1” tall & 117 Lbs. This bike is very lightweight compared to others that we looked at & it’s very easy for her to operate. The bike has more power than I thought it would have so that takes a small amount of time to adjust to. Overall we are both very happy with the bike so far. The bike was shipped without the front basket that was on back order so we expect that to be delivered sometime in Feb.

Never refunded my money

They sent the wrong bike. They had me buy another bike so I would have a box to return the wrong bike. I was told once it was returned. I would get a full refund.

Surfer 27.5” step-thru commuter ebike

Just put the bike together even though I has some problems installing the derailleur guard. The bike looks really pretty. It took about an hour for full charge. Took the first spin. It has a lot of power. It perhaps took only 2 seconds to reach 20Mph. I am really impressed!!

Improvements: The only item that was wrong was a screw on the bottom of the box. I figured it would have to be the steering column. It was one of the 4 screws to hold the handlebar on the bike. No big deal. Not sure how that got through QC.
The first Ride

I was a bit worried about the transport of the ebike from Califorina to Virginia as it was touched 6 times (went to various FedEx hubs until it was delivered to me. To my delight the package did not have any holes, and all was in fully in-tack. I opened the box and took everything out as the YouTube video illustrated. The only thing that needed slight adjustment was the back mud fender. The support wires were a little bent where the tire was rubbing against the fender. No big deal. I assembled it in 35 minutes only referring to the video and I'm pretty handy with fixing things. I finally took it out for a spend to see how the PAS works, throttle and gear shifts. I was pleasantly surprised that it had a lot of gusto in PAS 1 and got it up to 21 mph in seconds. I bought this bike for my wife (as she is 5'2" and 66 years old) the color is not my first choice, but she loves it (greenish). It is a bit cold here in Virginia and looking for a nice day to take her out and show her how it works. She is a bit worried that the bike is too heavy and (only 52 lbs) but she worries a lot. Once I get her up and running I will be in the market for a Fat tire ebike. (I am hoping there is a promotion soon!)

Recommendation score: DEPENDS ON SITUATION
Improvements: Front wheel held on with very thin bolt thru fork. 1/4”. ? No “keepers holding thru for in case nut comes loose. Can be a very dangerous situation if someone loses the front tire from the fork. Otherwise bike looks well built. Very disappointing no one has improved this
Nice bike

Poor design of front wheel to fork very dangerous

Surfer Dude!!

Arrived undamaged.
Parts don’t match build video (no rear nut protector covers, no handle bar alignment markings, etc.)
Derailer protector is advised to be installed by a bike shop. It should come pre installed or be marked as optional.
I spun the rear wheel and it seems to wobble. I have not ridden yet, but this is my biggest concern.
It looks great. My wife is 5’3” and it easily fits her with plenty of room to spare.
No instructions on how to install front light.
Not easy to align handle bar post. This is another concerning issue.

Surfer 27.5

Received my bike in less than a week. Instructions are OK, it helped watching utube videos of folks putting it together. Two people putting it together are much better than one. My 16 year old grandson helped me. The shim on the front fork was not noticed right away, once removed the wheel went on easily. As noted in the videos the kickstand is not self evident. Had the front fender rub the wheel, bent the from wire frame to straighten it out. Did order the bike with the front basket, it wasn’t with the bike, I will call them tomorrow. One other irritant was that I had a lower price a couple of days prior, just didn’t order it then and paid a higher but still discounted price. My grandson, son, and I rode it, WOW! Can’t wait to get it out for longer rides.

Stepthru Surfer

Excellent power and speed. Only problem I'd that I am 5' 2" and can't reach the ground when I stop. Seat is all the way down. Needs to be 1 inch lower.
