FREQUENTLY ASKED QUESTIONS : What do you need to know if you are moving to PAB

Updated: Apr 6

With a complete ban of PMD from footpaths, we saw large inquiries of users looking to switch to PABs. Many have asked us, and here are the top 21 frequently asked questions:

1. What is PAB?

PAB stands for Power Assisted Bicycles. It is basically a bicycle, a proven and tested transport apparatus in the last 200 years, modernized with added battery powered motor for extra convenience and comfort

2. What is PMD?

Personal Mobility Devices like electric scooter, unicycle, fiido, dyu, electric hoverboard and such are basically a battery dependent motorized gadget that evolves from around 20 years ago as improvement of play-toys

3. How are PAB and PMD different?

Like any bicycle, PAB relies on human to pedal (cycling) to move it. A good PAB is able to have seamless transition between motor and human pedal. PMDs do not have pedal to aid users. PMDs only depend on battery to power. Therefore, when run out of battery, PMD becomes a dead weight while PAB can still cycle through.

4. Does it have a throttle like PMD? How do you activate the motor assistance?

Under LTA regulation no throttle of any kind allowed for PABs. You get motor assistance when you start pedaling

5. What is the battery specification and charging time of PABs sold by TWD Bicycle?

Our three LTA approved PABs, SMART1S, SMART1SPLUS, MARS, are equipped with 7.8Ah 36Volt Lithium Ion battery and charging time is around 2 to 3 hours.

6. What is the distance user can expect before the battery need charging?

In average, users reported to get 50km to 60km for SMART1S, and 60 to 80km for MARS before the battery power is depleted. Distance achieved varies due to various reasons such as the total loads, road conditions, users power selections, frictions, and so on.

7. Why is my PMD with similar battery spec gets a third or half of TWD’s PAB distance only?

All three TWD Bicycle’ PABs, SMART1S, SMART1SPLUS and MARS, are equipped with premium components found in premium bicycles to minimize frictions. Therefore, they consume little battery power to overcome friction, and move forward not so much taxing on the battery. PMDs or lower quality PABs often gets high drag resistance and frictions, resulting in more battery power usage.

Due to shorter distance of PMD or lower grade PABs many are illegally modified with larger battery cramped into small space, often resulting in poor heat dissipation and often becoming fire hazard that endanger it users and their neighbors.

8. Does the battery conform to UL2272 safety requirements?

Yes Indeed, our PABs pass even more stringent and more extensive safety requirement. Our battery has been tested and passed with full mark, conforming to high European Safety Standard EN15194.

For more complete explanation on safety standard, you can refer to our article on this:

9. Does PABs from TWD Bicycle get affected by the ban?

10. Will the buyer able to use it beyond 31 Dec 2019?

11. As TWD Bicycle’s PABs look just like a normal bicycle with hidden motor and battery, can they be used in public footpath?

Although our PABs are of award-winning design and look like a normal bicycle, they are still categorised as powered/motorized therefore, not allowed in the over-crowded small public footpaths. They are however allowed in the extensive network of public share-paths, park connectors, bicycle paths and public roads. We urge our users to be mindful of regulations, and let’s create beautiful and courteous Singapore for everyone.

12. What are the advantages of PAB over PMD?

13. What is the price of PABs from TWD Bicycle?

For latest price and availability visit our online shop at

14. Why is the price being higher than PMDs?

Many factors determine price, such as quality, design, ergonomics, durability and reliability.

Even for manual bicycle, price ranges from hundreds of dollars to tens of thousands. Quality and user’s satisfaction vary following the price.

With regards to safety and ergonomics, PMDs may have hidden cost to user health due to bad seating position and lack of movements.

Although the initial investment of our PABs is higher, but the operational cost in the long run would be significantly lower due to lower replacement of parts like brake, tyres, battery which can add up significantly for PMDs

In addition, we tick all these important points: availability of local warranty, parts and service, components, ease of operation and maintenance, and overall user satisfaction.

We have written a blog article on the price and cost:

15. Do TWD’s Bicycle PABs include LTA registration?

Yes. Unlike PMDs that do not get inspected by LTA appointed inspection centre, every single unit of LTA-approved PAB sold through us still need to be inspected, sealed manually and registered with LTA. This strict enforcement are costly and involves a lot of special handling and transport and has not changed since 2016.

PMDs are not subjected to the same strict enforcement hence different rules and regulations for PABs and PMDs
