FAQ

While aluminum is lightweight and strong, it's stiff and doesn't absorb vibrations as well as steel. By using a more flexible material in the fork and thick rubber grips, minor road vibrations are dampened before they reach your hands.

That depends on how your define "off-road." Extremely rough or mountain biking conditions: No. The Tailwind was designed for commuting with a front fork that is not intended for mountain biking abuse. Hardpack trails, paths and dirt roads: You'll find the Tailwind to be a capable and reliable companion.

Not at this time. We got so excited about the e-bikes on our drawing board that we opted to manufacure all four models, rather than one model in several sizes.

This feature is only available on early models and was disabled on later models due to stress on the motor - which was chosen specifically to perform at 20mph. We are testing several new motors capable of higher perfomance speeds and may return this feature in the near future. It's not the display, it's the specs of our motor. When manufacturing motors, you choose between speed and torque. When you increase one, you decrease the other. Too much speed and you struggle up hills, too much torque and you sacrifice top end speed. Our motors are in the middle with equal emphasis on torque and speed. With the

Yes, to the lower 48 States!

We're currently in a temporary location in Costa Mesa, California. We're trying to find a permanent location that has safe surroundings for test rides, room for growth and is close to bike trails for commuting and test riding. We're closing in. Stay tuned. In the meantime, if you're local or going to be in the Costa Mesa area, give us a call. We'd be hapy to arrange a "private showing" and a long test ride!

Over a year of research, design and testing took place before Acey DC E-Bikes was officially started in Sept. of 2017. Our very first shipment of e-bikes was delivered in early 2018. Our first sale and outgoing shipment was made the same day.

Currently we have fewer than 10 employees, but we have big plans. We've invested heavily into production and we're set up for a strong future. We're proud to be a small American business and everything it represents. Our customers are our only investors and we provide the respect and service levels that title deserves.

If the spring is too tight, it will feel like sitting on a pogo stick and recoil from large bumps can almost lift you off the seat. If the spring is too loose, it will bottom out and not provide any suspension on larger bumps. Ideally, you want your full seated body weight (both feet on pedals, both hands on handlebar) to cause the spring to compress about half an inch. How to adjust: Under the bottom of the rubber boot (nearest the seat post) is a cap/ring that can be turned to fine-tune the spring tension. It screws towards the seat post, so when standing above the bike, clockwise tightens, counter-clockwise loosens. If you loosen too much, the cap will come off and it's a pain to reassemble! If you need more than fine-tuning to adjust (riders toward the light and heavy end of the spectrum), start by opening the quck release on the seat post and removing the seat and seat post. Turn it upside down and you will see a recessed disc/hex bolt. Use an 8mm hex wrench to stiffen the spring (clockwise) or loosen the spring (counter clockwise). Warning: do not loosen past the point where 0.25" of threading is visible inside the seat post and do not over-tighten or force. If you reach the end of the adjustment range and need to adjust beyond, Promax makes lighter and heavier springs that can replace the "Medium" spring they are sold with. Please contact Promax or your local bike shop for availability in your area.

The suspension seat post adds almost 1.5" to the length of the seat post - the amount it "travels" when hitting a bump. Replacing it with a standard seat post will allow you to lower the seat 1.5" more! With the adjustable handle bars on the Eclipse models and Tailwind, you'll be able to customize your fit and have a comfortable ride.

Personal experience. Our range projections are based on real world riding experience on the Santa Ana River Trail (SART) in Southern California. It's a relatively flat bike trail with light early morning breezes and an equal amount of tailwinds and headwinds. We set the displays so top speed was 25 MPH, making PAS level 4 peak at top trail speed of 20 MPH without pulling full wattage from the system. NOTE: When the system is the top PAS level and under strain, like climbing a hill or trying to maintain top speed into a strong headwind, the motor peaks at 720W, pulling significant power from the battery. This is great when needed, but often it's not. By riding in PAS level 4, there is "cap" on how much power the system can pull, providing plenty of assistance while saving significant battery power. Stronger winds, hills, rider weight, rider input (pedaling), level of assistance used, throttle usage... all affect battery life.
