  • So Much Fun
First thing is this bike is really a overall awesome ebike. This is my first ebike so I haven’t used others to compare. It was really easy to set up and it was packaged very well with no damage at all. The bike is a little bigger than I thought it would be and it looks awesome. I am 5’6” and I have the seat and handle bars at the lowest point and it feels great this way for me. So far I have only done a few test rides and I haven’t even tried all the mode/settings on it. Going slightly uphill for a long way it was right at 20 mph in pas4 mode and hitting a little over 24 going downhill on the same road. My brakes are rubbing a little but I did not try to do any adjustment on it yet. I rode with my 8 year old daughter on the back with no issues and we had a blast and are ready to get out and cruise around more. Like I said I have only rode a few times so far but if this review doesn’t change then everything is still going good with this ebike. ... show more

  • Great Ebike
Pros The e-bike is well designed and built. The battery size(30ah) is a big improvement over most other e-bike sold. It is a step thru frame which makes getting on easy, especially for this 70+yr old man. Also it is not difficult to maneuver even though it weighs 90lbs. It has a efficient 750 watt motor and is very water resistant and can be ridden in the rain. It is curvaceous and sexy looking, like a beautiful women. Being a retired scientist I give this e-bike a strong five stars. It did not come with the sticker which tells the make: Romatlink and model: Dalphin, class 3 E-bike rating, the 750 watt motor rating, the max speed 28mph, battery voltage (48V) and amp hour rating (30.Ah), max load. Please send me this sticker which by law is supposed to be applied to the bike so it can be viewed by enforcement officers. This sticker is to be supplied by the dealer or manufacturer according to Minnesota state law. ... show more

  • Good
Works well and helps me go farther. The front break needs work. Otherwise I am quite pleased with it for my first e-bike.

  • DO NOT DO BUSINESS WITH THIS COMPANY!
The bike I received does not work. I put everything together (there are no instructions included btw, just just kind of guess where things go). I charged the battery overnight, the light turned from red to green indicating that it had been fully charged. But then the bike would not turn on. No lights work, no display, no peddle assist. I tried to talk with the seller but they keep asking for more pictures and saying there is nothing wrong. I asked for a return, sent the bike back, and never got a refund. Amazon says they cannot do anything, so I am just out of the money and have no bike. ... show more

  • Good cruiser with large battery
I test and review ebikes. Especially ones under a grand. And this Ebike scored an 7.5/10 on our YouTube review for an Ebike under 1k. Would have scored higher with hydraulic brakes but ones on it are adequate. See YouTube video for In depth review.
