BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.

We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.

It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.

If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews

We have read all expert and user reviews on the DTTZH A12. In summary, this is what cyclists think. Published Jun 21, 2026 by Reda Ashour.

8 reasons to buy

The DTTZH A12 is available with a 52V 25Ah battery and 1,500W motor, or a 48V 15Ah battery and 750W motor.
The A12 comes with a key fob, fenders, lights, a phone holder, a passenger seat, and pegs.
Owners and reviewers appreciate the easy folding process and compact folded size for storage and transport.
The DTTZH A12 comes mostly assembled.
The A12 has UL 2849 certification, which isn't a guarantee at this price.
Owners are impressed by the 33mph top speed (48V build) after unlocking.
A reviewer feels the 1,500W motor provides good, usable power at the top end.
Buyers appreciate the low price.

12 reasons not to buy

With a maximum seat height of just 35.4”, the A12's 5’3” to 6’3” height range is exaggerated.
DTTZH warns their website may charge an extra international fee, and that payment failure is normal, and to continue trying.
The A12 is heavy at 62.83lb, especially to lift when folded.
Pedaling is inefficient due to the poor ergonomics, cheap cadence sensor, and single-speed drivetrain.
Owners report real-world range of just 8 to 12 miles from the 15Ah battery.
A reviewer of the 1,500W A12 says the motor is very sluggish off the line.
Two owners experience the wiring burning and see smoke. Customer support expects the buyer to replace the complicated wiring harness.
The manual has no assembly instructions and contains very little information.
Two buyers say their e-bikes aren’t working upon arrival. Another stops working after four days, with no response from the seller.
A buyer and tester complain the small wheels make for a rough ride.
A reviewer says the passenger seat is so small that it’s pointless.
A tester's bike has unfinished welds between the frame tubes.

Bottom line

The DTTZH A12 is a mini folding e-bike available with a 52V or 48V system. The A12 is highlighted for its compact folded size, low price, and included accessories, but that's where the praise ends. The biggest complaints about the A12 are that it’s smaller than buyers anticipate, heavy, and uncomfortable. The 48V build's range also disappoints. Multiple buyers receive non-functional or damaged bikes or quickly experience electrical malfunctions. Long-term durability is improbable, and with DTTZH’s questionable online presence, receiving support is too, making the A12 a risky investment.
